HMC356LP3

GaAs PHEMT MMIC LOW NOISE

AMPLIFIER, 350 - 550 MHz

v01.0604

General Description

Features

Functional Diagram

The HMC356LP3 high dynamic range GaAs

PHEMT MMIC Low Noise Amplifier is ideal for GSM

& CDMA cellular basestation and Mobile Radio

front-end receivers operating between 350 and 550

MHz. This LNA has been optimized to provide 1.0

dB noise figure, 17 dB gain and +38 dBm output IP3

from a single supply of +5.0V @ 104 mA. Input and

output return losses are 15 dB typical, with the LNA

requiring only four external components to optimize

the RF input match, RF ground and DC bias. The

HMC356LP3 shares the same package and pinout

with the HMC372LP3 high IP3 LNA. A low cost,

leadless 3x3 mm (LP3) SMT QFN package houses

the low noise amplifier.
