AMGP-6432 28-31 GHz 2W SMT Packaged Power Amplifier
Data Sheet
Description
The AMGP-6432 is a surface mount packaged 2-Watt power amplifier that operates from frequencies between 28 to 31 GHz. In the operational frequency band from 29.25 to 30 GHz, it provides 33 dBm of typical output power (P1dB)/ 34 dBm Psat and 21.5dB of small-signal gain. This PA is also suitable for high linear application where the PA demonstrates greater than than -38dBc of third order output inter modulation (OIM3) at +18dBm/ tone output power level.
