Product Description
SPA-1218
1960 MHz 1 Watt Power Amplifier
with Active Bias
Sirenza Microdevices’ SPA-1218 is a high efficiency GaAs
Heterojunction Bipolar Transistor (HBT) amplifier housed in
a low-cost surface-mountable plastic package. These HBT
amplifiers are fabricated using molecular beam epitaxial
growth technology which produces reliable and consistent
performance from wafer to wafer and lot to lot.
This product is specifically designed for use as a driver
amplifier for infrastructure equipment in the 1960 MHz PCS
band. Its high linearity makes it an ideal choice for multi-carrier
and digital applications.

Description
Device Schematic
Vcc
VCC is the supply voltage for the active bias network.
Bypassing in the appropriate location as shown on
application schematic is required for optimum RF
performance.

Vbias
Vbias is the bias control pin for the active bias network.
Device current is set by the current into this pin.
Recommended configuration is shown in the Application
Schematic. Bypassing in the appropriate location as
shown on application schematic is required for optimum
RF performance.

RF In
N/C
RF input pin. This pin requires the use of an external
DC blocking capacitor chosen for the frequency of
operation.
3
No connection
5, 6, 7, 8 RF Out/Vcc RF output and bias pin. Bias should be supplied to this
pin through an external RF choke. Because DC biasing
is present on this pin, a DC blocking capacitor should
be used in most applications (see application
schematic). The supply side of the bias network should
be well bypassed. An output matching network is
necessary for optimum performance.
EPAD
Gnd
Exposed area on the bottom side of the package needs
to be soldered to the ground plane of the board for
thermal and RF performance. Several vias should be
located under the EPAD as shown in the recommended
land pattern (page 7).

Operation of this device beyond any one of these limits may cause
permanent damage. For reliable continuous operation, the device
voltage and current must not exceed the maximum operating values
specified in the table on page one.
Bias Conditions should also satisfy the following expression:
ICCVCC (max) < (TJ - TL)/Rth,j-l
