GaAs PHEMT MMIC LOW NOISE

AMPLIFIER w/ BYPASS MODE, 3.3 - 3.8 GHz

v03.0309

General Description

Features

Functional Diagram

The HMC593LP3(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 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 +5V @ 40mA. Input and output

return losses are 23 and 13 dB respectively with no

external matching components required. A single

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

mode and a low 2 dB loss bypass mode reducing the

current consumption to 10 μA.
