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.
