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 (P
1dB
)/ 34 dBm P
sat
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.
