HMC311LP3

InGaP HBT GAIN BLOCK

MMIC AMPLIFIER, DC - 6.0 GHz

v01.0604

General Description

Features

Functional Diagram

The HMC311LP3 is a GaAs InGaP Heterojunction

Bipolar

Transistor

(HBT)

Gain

Block

MMIC

SMT DC to 6 GHz amplifier. This 3x3mm QFN

packaged amplifier can be used as either a

cascadable 50 Ohm gain stage or to drive the

LO of HMC mixers with up to +17 dBm output

power. The HMC311LP3 offers 14.5 dB of gain

and an output IP3 of +30 dBm while requiring

only 56 mA from a +5V supply. The Darlington

feedback pair used results in reduced sensitivity

to normal process variations and yields excellent

gain stability over temperature while requiring a

minimal number of external bias components.

P1dB Output Power: +15.5 dBm

Output IP3: +32 dBm

Gain: 14.5 dB

Typical Applications

The HMC311LP3 is an ideal RF/IF gain block

or LO buffer amplifier for:

• Cellular / PCS / 3G

• Fixed Wireless & WLAN

• CATV & Cable Modem

• Microwave Radio
