General Description
The TriQuint TGA4534-SM is a K-Band Power
Amplifier with integrated power detector. The
TGA4534-SM operates from 17.7 - 19.7 GHz and is
designed using TriQuint’s power pHEMT production
process.
The TGA4534-SM typically provides 34 dBm of
saturated output power with small signal gain of 21
dB. Third Order Intercept is 42.5 dBm at 23 dBm
SCL.
The TGA4534-SM is available in a low-cost, surface
mount 28 lead 5x5 mm QFN package and is ideally
suited for Point-to-Point Radio.
Lead-free and RoHS compliant
Evaluation Boards are available upon request.
