General Description

The HMC308 & HMC308E are low cost MESFET MMIC amplifiers that operate from a single +3 to +5V supply from 0.8 to 3.8 GHz. The surface mount SOT26 amplifier can be used as a broadband amplifi er stage or used with external matching for optimized narrow band applications. With Vdd biased at +5V, the HMC308 & HMC308E offers 18 dB of gain and +20 dBm of saturated output power while requiring only 53 mA of current. This amplifi er is ideal as a driver amplifi er for transmitters or for use as a local oscillator (LO) amplifi er to increase drive levels for passive mixers. The amplifi er occupies 0.014 in2 (9 mm2), making it ideal for compact radio designs.
