GENERAL DESCRIPTION
The ADPA7007 is a gallium arsenide (GaAs), pseudomorphic
high electron mobility transfer (pHEMT), monolithic microwave
integrated circuit (MMIC), 31.5 dBm saturated output power
(>1 W) power amplifier, with an integrated temperature
compensated, on-chip power detector that operates between
20 GHz and 44 GHz. The ADPA7007 provides 20.5 dB of small
signal gain and approximately 32 dBm of saturated output power
at 32 GHz from a 5 V supply (see Figure 26). The ADPA7007
has an output IP3 of 42.5 dBm and is ideal for linear
applications such as electronic countermeasure and
instrumentation applications requiring >30 dBm of efficient
saturated output power. The RF input/outputs are internally
matched and dc blocked for ease of integration into higher level
assemblies. The ADPA7007 is packaged in a 7 mm × 7 mm,
18-terminal ceramic leadless chip carrier with heat sink
(LCC_HS) that exhibits low thermal resistance and is
compatible with surface-mount manufacturing techniques.

THEORY OF OPERATION
The simplified architecture of the ADPA7007 power amplifier
is shown in Figure 54. The ADPA7007 is a cascaded, three-
stage amplifier with a combined gain of 21.5 dB and a PSAT
value of 31.5 dBm.
A portion of the RF output signal is directionally coupled to a
diode for detection of the RF output power. When the diode is
dc biased, the diode rectifies the RF power and makes the RF
power available for measurement as a dc voltage at VDET. To
allow temperature compensation of VDET, an identical and
symmetrically located circuit (minus the coupled RF power) is
available via VREF. The difference of VREF − VDET provides a
temperature compensated signal that is proportional to the RF
output.
The drain current is controlled by the voltage on the VGG1 and
VGG2 pins. These pins must be connected together and driven
by a negative voltage in the −1.5 V to 0 V range (typical gate
bias voltage for a quiescent drain current bias of 1400 mA is
−0.685 V). Simplified bias pin connections to the dedicated
gain stages are shown in Figure 54.
To obtain optimal performance from the ADPA7007 and avoid
damaging the device, follow the recommended biasing
sequences described in the Applications Information section.

APPLICATIONS INFORMATION
Figure 55 shows the basic connections for operating the
ADPA7007. All measurements for this device were taken using
the typical application circuit shown in Figure 55.
The following is the recommended bias sequence during
power-down:
1. Turn off the RF signal.
Capacitive bypassing is required for all VGGx and VDDx pins. VGG1
and VGG2 are the gate bias pins, and VDD1 to VDD6 are the drain
bias pins for the cascaded amplifier.
2. Decrease the gate bias voltages, VGG1 and VGG2, to −1.5 V to
achieve an IDQ = 0 mA (approximately).
3. Decrease all drain bias voltages to 0 V.
4. Increase the VGGx gate bias voltage to 0 V.
The power supply and gate voltage decoupling capacitors
shown in Figure 55 represent the configuration that was used to
characterize and qualify the device. There may be scopes to
reduce the number of capacitors, but scopes vary from system
to system. It is recommended to first remove or combine the
largest capacitors that are farthest from the device. The
following is the recommended bias sequence during power-up:
The VDD = 5 V and IDQ = 1400 mA bias conditions are recom-
mended to optimize overall performance when the gate voltage
is being held at a fixed value (note that with the gate voltage held at
a fixed value, the drain current, IDD, increases as the RF input
power level is increased, as shown in Figure 41). Unless otherwise
noted, the data shown was taken using the recommended bias
conditions. Operation of the ADPA7007 at different bias
conditions can result in different performance. Biasing the
ADPA7007 for higher quiescent drain current typically results
in higher gain and output P1dB at the expense of increased
power dissipation (see Table 8).
1. Connect the power supply ground to circuit ground (GND).
2. Set the gate bias voltages, VGG1 and VGG2, to −1.5 V.
3. Set all drain bias voltages (VDDx) to 5 V.
4. Increase the gate bias voltage to achieve the quiescent
supply current and set IDQ = 1400 mA.
5. Apply the RF signal.

BIASING ADPA7007 WITH THE HMC980LP4E
The HMC980LP4E is an active bias controller that measures
and regulates drain current by automatically adjusting the gate
voltage. The HMC980LP4E can control the biasing of RF
amplifiers with drain voltages up to 16.5 V and currents up to
1.6 A. The controller provides constant drain current biasing
over temperature and device to device variation, and properly
sequences gate and drain voltages to ensure the safe operation
of the amplifier.
Two HMC980LP4E devices are needed to support current
levels at 1800 mA because a single HMC980LP4E device can
support a maximum current of 1600 mA. In the application
circuit shown in Figure 56 and Figure 57, the ADPA7007 drain
voltage and drain current are set by the following equations:
VDRAIN = VDD − IDRAIN × 0.85 Ω
where:
VDRAIN = 5 V, the drain voltage from Pin 17 and Pin 18 of the
(1)
The HMC980LP4E offers self protection in the event of a short
circuit, as well as an internal charge pump that generates the
negative voltage required on the gate of the ADPA7007. The
HMC980LP4E also provides the option to use an external
negative voltage source. The HMC980LP4E is also available in
die form as the HMC980.

LIMITING VGATE AND VNEG FOR ADPA7007 VGGX
ABSOLUTE MAXIMUM RATING REQUIREMENT
Although the ADPA7007 is specified with a quiescent drain
current of 1400 mA, the operational drain current, IDRAIN, required
to achieve the maximum output power from the ADPA7007
must be set closer to 1800 mA. The IDRAIN current increases to
approximately 1800 mA when the RF input power is 15 dBm,
the approximate input compression point (see Figure 41). As a
result, a target IDRAIN of 1800 mA is chosen.
When using the HMC980LP4E to control the ADPA7007, set
the minimum voltages for the VNEG and VGATE pins of the
HMC980LP4E to −1.5 V to keep these voltages within the absolute
maximum rating limits for the VGGx pins of the ADPA7007. To
set the minimum voltages, use the R15 and R16 resistors shown
in Figure 56 and Figure 57. Refer to the AN-1363 Application
Note, Meeting Biasing Requirements of Externally Biased
RF/Microwave Amplifiers with Active Bias Controllers, for more
information and calculations for R15 and R16.

The dc supply sequencing in the Power-Up Sequence section
and the Power-Down Sequence section is required to prevent
damage to the HMC980LP4E when using it to control the

The power-up sequence is as follows:
1. Set VDIG (Pin 9) of both HMC980LP4E devices to 3.3 V.
2. Set the VDD pins of both HMC980LP4E devices to
5.765 V.
3. Set VNEG (Pin 15) of both HMC980LP4E devices to
−1.5 V. This step is not needed if using an internally
generated voltage.
4. Set EN (Pin 5) of both HMC980LP4E devices to 3.3 V
(transitioning from 0 V to 3.3 V turns on VGATE and
VDRAIN).

CONSTANT DRAIN CURRENT BIASING vs.
CONSTANT GATE VOLTAGE BIASING
Power-Down Sequence
The HMC980LP4E uses a feedback loop to continuously adjust
VGATE to maintain a constant drain current over dc supply
variation, temperature, RF input/output level, and device to
device variation. Constant drain current bias is the preferred
method for reducing time in calibration procedures and for
maintaining consistent performance over time.
The power-down sequence is as follows:
1. Set EN (Pin 5 of both HMC980LP4E devices) to 0 V
(transitioning from 3.3 V to 0 V turns off VDRAIN and
VGATE).
2. Set VNEG (Pin 15 of both HMC980LP4E devices) to 0 V.
This step is not needed if using an internally generated
voltage.
In comparison to a constant gate voltage bias, where the current
increases when RF power is applied, a constant drain current has
a slightly lower output P1dB. This output P1db is shown in
Figure 63, where the RF performance is slightly lower than
constant gate bias voltage operation due to a lower drain current at
high input power (see Figure 60) as the HMC980LP4E reaches
1 dB compression.
3. Set the VDD pins of both HMC980LP4E devices to 0 V.
4. Set VDIG (Pin 9 of both HMC980LP4E devices) to 0 V.
When the HMC980LP4E bias control circuit is set up, toggle
the bias to the ADPA7007 on or off by applying 3.3 V or 0 V,
respectively, to the EN pin of the HMC980LP4E. At EN = 3.3 V,
the VGATE pin of the HMC980LP4E drops to −1.5 V and the
VDRAIN pin of the HMC980LP4E turns on at 5 V. VGATE
then rises until IDRAIN = 1800 mA, and the closed control loop
regulates IDRAIN at 1800 mA. When EN = 0 V, VGATE is set to
−1.5 V, and VDRAIN is set to 0 V (see Figure 58 and Figure 59).
The output P1dB performance for constant drain current bias
can be increased toward constant gate voltage bias performance
by increasing the set current toward the IDD value it reaches
under RF drive in the constant gate voltage bias condition (see
Figure 63).
The limit of increasing drain current under the constant
current operation is set by the thermal limitations found in
Table 4 with the maximum power dissipation specification. As
the IDD increase continues, the actual output P1dB does not
continue to increase indefinitely but the power dissipation
increases linearly. Therefore, take the trade-off between the
power dissipation and output P1dB performance into
consideration when using constant drain current biasing.
