GaAs PHEMT MMIC LOW NOISE

AMPLIFIER w/ BYPASS MODE, 2.3 - 2.7 GHz

v01.0707

General Description

Features

Functional Diagram

The HMC605LP3 / HMC605LP3E are versatile, high

dynamic range GaAs MMIC Low Noise Amplifiers

that integrate a low loss LNA bypass path on the IC.

The amplifier is ideal for WiBro & WiMAX receivers

operating between 2.3 and 2.7 GHz and provides

1.1 dB noise figure, 20 dB of gain and +31 dBm output

IP3 from a single supply of +5.0V @ 74 mA. Input

and output return losses are 14 and 15 dB respectively

with no external matching components required. A

single control line (Vctl) is used to switch between LNA

mode and a low 2.0 dB loss bypass mode and reduces

the current consumption to 10 μA. The HMC605LP3 is

failsafe and will default to the bypass mode with no DC

power applied.

Output IP3: +31 dBm
