HMC311LP3 / 311LP3E

v05.1213

InGaP HBT GAIN BLOCK

MMIC AMPLIFIER, DC - 6 GHz

General Description

Features

Functional Diagram

The HMC311LP3(E) is a GaAs InGaP Heterojunction

Bipolar

Transistor

(HBT)

Gain

Block

MMIC

SMT DC to 6 GHz amplifiers. 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(E) offers 14.5 dB of gain and an output

IP3 of +32 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

50 Ohm I/O’s

Typical Applications

The HMC311LP3(E) is ideal for:

• Cellular / PCS / 3G

• Fixed Wireless & WLAN

• CATV & Cable Modem

• Microwave Radio
