GENERAL DESCRIPTION
The HMC7748 is a multistage power amplifier (PA) that provides 25 W of saturated output power across the band of 2 GHz to 6 GHz. It draws 0.7 A from a 12 V supply and up to 4 A from a 28 V supply. Input signals of as much as −8 dBm are acceptable, and the module has small signal gain of 60 dB.
The 12 V supply is regulated internally and generates the negative
voltage required for the gate bias. Built-in bias sequencing prevents the drain
voltages for the amplifier stages f...
