Product Description
S-parameters (dB)
The TriQuint TGA4522 is a compact Driver
Amplifier MMIC for Ka-band and Q-band
applications. The part is designed using TriQuint’s
0.15um power pHEMT production process.
The TGA4522 nominally provides 27.5 dBm
saturated output power, and 27 dBm output power
at 1dB Gain compression @ 38 GHz. It also has
typical gain of 18 dB, and return loss of 15 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.
The TGA4522 is 100% DC and RF tested on-wafer
to ensure performance compliance.
Lead-Free & RoHS compliant.
