LTC5536
600MHz to 7GHz
Precision RF Detector with
Fast Comparator Output
U
FEATURES
DESCRIPTIO
The LTC®5536 is an RF power detector for RF applications
operating in the 600MHz to 7GHz range. A temperature
compensated Schottky diode peak detector and fast com-
parator are combined in a small ThinSOTTM package. The
supply voltage range is optimized for operation from a
single cell lithium-ion or three cell NiMH battery.
■
Temperature Compensated Internal Schottky
Diode RF Detector
■
Wide Input Frequency Range: 600MHz to 7GHz*
■
Wide Input Power Range: –26dBm to 12dBm
■
Fast Comparator Output with Latch Enable
■
25ns Response Time with 0dBm RF Input Level
■
Rail-to-Rail Output Swing
The RF input voltage is peak detected using an on-chip
Schottky diode. The detected voltage is compared against
a reference voltage at VM.
■
Comparator Output Current: ±20mA
■
Wide VCC Range of 2.7V to 5.5V
■
Low Operating Current: 2mA
■
TheresponsetimefromtheRFinputtoVOUT canbeaslittle
as 20ns. The comparator output is latched when LEN is
high or is transparent when LEN is low.
Available in a Low Profile (1mm) SOT-23 Package

LEN (Pin 4): Latch Enable Input. Output is latched when
RFIN (Pin 1): RF Input Voltage. Referenced to VCC. A
coupling capacitor must be used to connect to the RF
signal source. The frequency range is 600MHz to 7GHz.
This pin has an internal 500Ω termination, an internal
Schottky diode detector and a peak detector capacitor.
LEN is high and transparent when LEN is low.
VOUT (Pin 5): Comparator Output.
VCC (Pin 6): Power Supply Voltage, 2.7V to 5.5V.
VCC should be bypassed appropriately with ceramic
capacitors.
GND (Pin 2): Ground.
VM (Pin 3): Comparator Negative Input. Apply reference
voltage to this pin.

Operation
operation of the comparator (no latching action), the LEN
pin should be connected to ground.
The LTC5536 is configured as a fast detector and high
speed comparator for RF power detection and RF power
alarms. The product integrates several functions to pro-
vide RF power detection over frequencies ranging from
600MHz to 7GHz. These functions include an RF Schottky
diodepeakdetector,alevelshiftamplifiertoconverttheRF
input signal to low frequency, and a fast comparator. The
LTC5536 provides a comparator reference input VM and a
latch enable input LEN.
The comparator output (VOUT) rise and fall times are
approximately 2ns (unloaded). The propagation delay for
the comparator alone was characterized by applying a
continuous 2GHz RF signal to the RFIN input. Then a 1MHz
square wave (0V to 2.5V) was applied to the VM input to
switch the comparator. Note that there is a signal inver-
sion, because the VM pin is connected internally to the
negative comparator input. The time delay from the tran-
sition edge of the square wave at the VM input to the
corresponding VOUT output transition (rising or falling) is
shown in Table 1.
RF Detector
The internal RF Schottky diode peak detector and level
shift amplifier convert the RF input signal to a low fre-
quency signal. The detector demonstrates excellent effi-
ciency and linearity over a wide range of input power. The
Schottky diode is biased at about 55µA, and drives a 15pF
internal peak detector capacitor.

The fast internal comparator compares the external refer-
ence voltage at VM to the internal signal voltage from the
peak detector, and produces the output signal, VOUT. The
internalpeakdetectorvoltageisfactorytrimmedto100mV
with no RF signal present. The comparator has approxi-
mately10mVofhysteresis,withatypicalVOUTlow-to-high
switching point of 100mV and a VOUT high-to-low switch-
ing point of 90mV with no RF signal present.
Overall Propagation Delay and Response Time
Figure 2 shows measurements of total propagation delay
from the RFIN signal input to the VOUT output of the
LTC5536, plotted as a function of RF input power. The
response is shown for RF Signal Absent-to-RF Signal
Present Transitions (Rising Edge VOUT), and for RF Signal
Present-to-RF Signal Absent Transitions (Falling Edge
VOUT). The LTC5536’s RF detector is optimized as a
positivepeakdetector.Consequently,thedeviceresponds
to a rising signal at the RF input much more rapidly than
to a falling signal. Correspondingly, Rising Edge VOUT
transitions are much more rapid than Falling Edge transi-
tions, as shown in Figure 2. The minimum propagation
delay is about 20ns at room temperature, in response to
strong overdrive conditions at the RFIN input. These
results were measured by applying a 1GHz RF signal that
was amplitude modulated by a 1MHz square wave with
50% duty cycle. An example time domain waveform is
shown in Figure 3.

Higher Frequency Operation
as a 100pF ceramic, is recommended, in parallel with a
larger capacitor (e.g., 0.1µF).
Operation of the LTC5536 at higher frequencies, to 12GHz
or above, is possible with reduced performance. Figure 4 Avoid ground bounce problems by proper attention to

output, VOUT, may be increased by means of an output
R-C low pass filter.
High Speed Design Techniques
As with all high speed comparators, careful attention to
printed circuit board layout and design is important in
order to ensure signal integrity. The most common prob-
lem involves insufficient power supply bypassing. Bypass
capacitors should be placed as close as possible to the
LTC5536 VCC pin. A good high frequency capacitor, such
Poor trace routes and high source impedances are also
common sources of problems. Keep all trace lengths as
short as possible and avoid running the output trace close
to the VM or the LEN traces on the PC board. Also, keep the
VM sourceimpedancelowanddecoupletheVM pinwithan
appropriate capacitor if necessary.
