General Description
The TriQuint TGA2752-SM is a C-Band Power
Amplifier with integrated power detector. The
TGA2752-SM operates from 7.1 – 8.5 GHz and is
designed using TriQuint’s power GaAs pHEMT and
GaN HEMT production processes.
The TGA2752-SM typically provides 40 dBm of
saturated output power with small signal gain of 28
dB. Third Order Intercept is 48 dBm at 30 dBm SCL.
The TG2752-SM is available in a low-cost, surface
mount 42 lead 7x9 QFN package and is ideally
suited for Point-to-Point Radio.
Lead-free and RoHS compliant

Vg12 can be biased from either side (pin 10 or pin 42), and the non-biased side can be left open.
Vd1, Vd2, and Vd3 must be biased from both sides.
Bias-up Procedure
Vg12 set to -1.5 V
Vg3 set to -3.5 V
Vd1, Vd2 set to 6 V
Vd3 set to 28 V
Adjust Vg12 more positive until quiescent Id is 1000 mA.
This will be ~ Vg = -0.65 V typical
Adjust Vg3 more positive until quiescent Id is 190 mA.
This will be ~ Vg = -2.6 V typical
Apply RF signal
Bias-down Procedure
Turn off RF signal
Reduce Vg12 to -1.5V. Ensure Id ~ 0 mA
Reduce Vg3 to -3.5V. Ensure Id ~ 0 mA
Turn Vd1, Vd2, Vd3 to 0 V
Turn Vg12, Vg3 to 0 V
