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.
