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 amplifier stage or used with external matching for optimized narrow band applications. With Vdd biased at +5V, the HMC308 & HMC308E offers 18 d B of gain and +20 d Bm of saturated output power while requiring only 53 m A of current. This amplifier is ideal as a driver amplifier for transmitters or for use as a local oscillator (LO) amplifier to increase drive levels for passive mixers. The amplifier occupies 0.014 in2 (9 mm2), making it ideal for pact radio designs.
