25 Watt Linear Power Amplifier
WIRELESS APPLICATIONS
Stealth Microwave’s
SM1822-44
is a 1.80
to 2.2 GHz solid state GaAs amplifier
designed for the various wireless markets.
Its compact size and high linearity make it
ideally suited for systems using CDMA,
OFDM, TD-CDMA, WCDMA, and
WiMAX standards. The amplifier provides
+44 dBm of output power at P1dB, 45 dBm
of Linear Gain, and an OIP3 of +55 dBm.
