General Description
The TriQuint TGA4544-SM is a Ka-Band Power
Amplifier with integrated power detector. The
TGA4544-SM operates from 26 – 31 GHz and is
designed using TriQuint’s power pHEMT production
process.
The TGA4544-SM typically provides 32 dBm of
saturated output power with small signal gain of 23
dB. Third Order Intercept is 41 dBm at 20 dBm SCL.
The TGA4544-SM is available in a low-cost, surface
mount 26 lead 5x5 ACQFN package and is ideally
suited for Point-to-Point Radio.
Lead-free and RoHS compliant
Evaluation Boards are available upon request.

Bias-up Procedure
Bias-down Procedure
Vg set to -1.5 V
Turn off RF supply
Vd set to +6 V
Reduce Vg to -1.5 V. Ensure Id ~ 0 mA
Adjust Vg more positive until quiescent Id is 1100 mA.
This will be ~ Vg = -0.58 V typical
Turn Vd to 0 V
Apply RF signal to RF Input
Turn Vg to 0 V

PCB Mounting Pattern
Notes:
1. The pad pattern shown has been developed and tested for optimized assembly at TriQuint Semiconductor. The PCB
land pattern has been developed to accommodate lead and package tolerances. Since surface mount processes vary
from company to company, careful process development is recommended.
2. Ground vias are critical for the proper performance of this device. Vias have a final plated thru diameter of .25 mm
(.010”).
