GaAs PHEMT MMIC LOW NOISE

AMPLIFIER, 700 - 1000 MHz

v02.0605

General Description

Features

Functional Diagram

The HMC372LP3 & HMC372LP3E are GaAs PHEMT

MMIC Low Noise Amplifiers that are ideal for GSM

& CDMA cellular basestation front-end receivers

operating between 700 and 1000 MHz. The amplifier

has been optimized to provide 1.0 dB noise figure, 15

dB gain and +34 dBm output IP3 from a single supply

of +5.0V @ 100 mA. Input and output return losses are

25 and 14 dB respectively with the LNA requiring only

four external components to optimize the RF Input

match, RF ground and DC bias. The HMC372LP3 &

HMC372LP3E share the same package and pinout

with the HMC356LP3 high IP3 LNA. A low cost,

leadless 3x3 mm (LP3) SMT QFN package houses

the low noise amplifier.
