Product Description

The TriQuint TGA4517 is a compact High

Power Amplifier MMIC for Ka-band

applications. The part is designed using

TriQuint’s 0.15um gate power pHEMT process.

The TGA4517 nominally provides 35dBm of

Saturated Output Power, and 20dB small

signal gain @ mid-band of 31 - 37GHz. The

MMIC also provides 12dB Return Loss.

The part is ideally suited for markets such as

Point-to-Point Radio, Military Radar Systems,

and Ka-Band Satellite Communications both

commercial and military.
