TGA4505 Datasheet, PDF (1/9 Pages) TriQuint Semiconductor – 4 Watt Ka Band HPA

4 Watt Ka Band HPA
Product Description
The TriQuint TGA4505 is a compact 4
Watt High Power Amplifier MMIC for Ka-
band applications. The part is designed
using TriQuint’s proven standard 0.25 um
gate Power pHEMT production process.
The TGA4505 provides a nominal 35.5
dBm of output power at 1 dB gain
compression from 24-32 GHz with a small
signal gain of 23 dB.
The part is ideally suited for low cost
emerging markets such as base station
transmitters for satellite ground terminals
and point to point radio.
The TGA4505 is 100% DC and RF tested
on-wafer to ensure performance
compliance.
Lead-free and RoHS compliant.
