AMGP-6434

28-31 GHz 4W SMT Packaged Power Amplifier

Data Sheet

Description

Features

The AMGP-6434 is a surface mount packaged 4-Watt power amplifier that operates from frequencies between 28 to 31 GHz. In the operational frequency band from 29.5 to 30 GHz, it provides 35.5 dBm of typical output power (P1dB)/36 dBm Psat and 19 dB of small-signal gain. This PA is also suitable for high linear application where the PA demonstrates greater than than -40 dBc of third order output inter modulation (OIM3) at +20 dBm/tone output power level.
