HMC604LP3 / 604LP3E

v00.0308

GaAs PHEMT MMIC LOW NOISE

AMPLIFIER w/ BYPASS MODE, 4.8 - 6.0 GHz

General Description

Features

Functional Diagram

Typical Applications

The HmC604lp3(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 wimAX & C-band radio receivers

operating between 4.8 and 6.0 GHz and provides

1.5 dB noise figure, 15 dB of gain and +26 dBm ip3

from a single supply of +5V @ 42mA. input and output

return losses are 12 and 14 dB respectively with no

external matching components required. A single

control line (0/Vdd) is used to switch between lNA

mode and a low loss bypass mode which reduces the

current consumption to 10 µA.

Noise figure: 1.5 dB

output ip3: +26 dBm

Gain: 15 dB

• wimAX/C-band radio

• fixed wireless

• Tower mounted Amplifiers

• public safety infrastructure

• Telematics & DsrC
