Product Description
The TriQuint TGA4905-CP is a compact
4 Watt High Power Amplifier Packaged
MMIC for Ka-band applications. The part
is designed using TriQuint’s proven
standard 0.25 um gate Power pHEMT
production process.
The TGA4905 provides a nominal 36
dBm of output power at an input power
level of 18 dBm from 25-31 GHz with a
small signal gain of 22 dB.
The part is ideally suited for low cost
emerging markets such as base station
transmitters for satellite ground terminals,
point to point radio and LMDS.
