GaAs PHEMT MMIC LOW NOISE

AMPLIFIER, 700 - 1000 MHz

v03.0610

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 dB noise figure, 15

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

of +5V @ 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. For applications

which require improved noise figure, please see the

HMC617LP3(E).

Noise Figure: < 1 dB

Output IP3: +34 dBm

Gain: 15 dB

Very Stable Gain vs. Supply & Temperature

Single Supply: +5V @ 100 mA

50 Ohm Matched Output

Typical Applications

The HMC372LP3 / HMC372LP3E is ideal for

basestation receivers:

• GSM, GPRS & EDGE

• CDMA & W-CDMA

• Private Land Mobile Radio
