GaAs PHEMT MMIC LNA w/

FAILSAFE BYPASS MODE, 1700 - 2200 MHz

v04.0709

General Description

Features

Functional Diagram

The HmC669lp3(e) is a versatile, high dynamic range

GaAs mmiC low Noise Amplifier that integrates a

low loss lNA bypass mode on the iC. The amplifier

is ideal for receivers and lNA modules operating be-

tween 1.7 and 2.2 GHz and provides 1.4 dB noise

figure, 17 dB of gain and +29 dBm ip3 from a single

supply of +5V @ 86mA. input and output return losses

are excellent and no external matching components

are required. A single control line is used to switch

between lNA mode and a low loss bypass mode.

failsafe topology also enables the lNA bidirectional

bypass path when no DC power is available.

Noise figure: 1.4 dB

output ip3: +29 dBm

Gain: 17 dB

failsafe operation:

Bypass is enabled when lNA is unpowered

single supply: +3V or +5V

Typical Applications

The HmC669lp3(e) is ideal for:

• Cellular/3G and lTe/wimAX/4G

• BTs & infrastructure

• repeaters and femtocells

• Tower mounted Amplifiers

• Test & measurement equipment
