The TriQuint TGA4538 operates from 37 to 40 GHz and is designed using TriQuint's 3MI power pHEMT production process. The TGA4538 provides a nominal 29.5 dBm of saturated power with a small signal gain of 24 dB at Vd = 5 V and Idq = 600 mA. When biased at 6 V and 600 mA, TGA4538 provides a nominal 30.5 dBm of saturated power with a small signal gain of 24 dB.

The TGA4538 is suitable for a variety of systems such as point-to-point radio and millimeter-wave communications.

The TGA4538 is 100% DC and RF tested on-wafer to ensure performance compliance. The TGA4538 has a protective surface passivation layer providing environmental robustness. The part is lead-free and RoHS compliant. Evaluation boards are available upon request.
