Product Description
The TriQuint TGA4522-EPU is a compact Driver
Amplifier MMIC for Ka-band and Q-band
applications. The part is designed using TriQuint鈥檚
proven standard 0.25um power pHEMT production
process.
The TGA4522-EPU nominally provides 27 dBm
saturated output power, and 26 dBm output power
at 1dB Gain compression @ 38 GHz. It also has
typical gain of 14 dB, and return loss of 12 dB.
The part is ideally suited for low cost emerging
markets such as Digital Radio, Point-to-Point
Radio and Point-to-Multi Point Communications.
