GaAs PHEMT MMIC LOW NOISE

AMPLIFIER w/ BYPASS MODE, 3.3 - 3.8 GHz

v00.0407

General Description

Features

Functional Diagram

The HMC593LP3 / HMC593LP3E are versatile, high

dynamic range GaAs MMIC Low Noise Amplifiers

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

The amplifier is ideal for WiBro & WiMAX receivers

operating between 3.3 and 3.8 GHz and provides 1.2

dB noise figure, 19 dB of gain and +29 dBm IP3 from

a single supply of +5.0V @ 40mA. Input and output

return losses are 23 and 13 dB respectively with no

external matching components required. A single

control line (0/+3V) is used to switch between LNA

mode and a low 2.0 dB loss bypass mode reducing

the current consumption to 10 μA.
