GENERAL PURPOSE 100 mW GaAs

MMIC AMPLIFIER, 0.8 - 3.8 GHz

v05.1107

General Description

Features

Functional Diagram

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 ampli-

fier stage or used with external matching for opti-

mized narrow band applications. With Vdd biased at

+5V, the HMC308 & HMC308E offers 18 dB of gain

and +20 dBm of saturated output power while requir-

ing only 53 mA 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

Gain: 18 dB

P1dB Output Power: +17 dBm@ +5V

Single Supply: +3V or +5V

No External Components

Integrated DC Blocks

Ultra Small Package: SOT26

Typical Applications
