GaAs PHEMT MMIC LOW NOISE

AMPLIFIER, 700 - 1000 MHz

v00.1005

General Description

Features

Functional Diagram

The HMC376LP3 & HMC376LP3E 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 0.7 dB noise figure,

15 dB gain and +36 dBm output IP3 from a single

supply of +5.0V. Input and output return losses are 14

and 12 dB respectively and the LNA requires only one

external component to optimize the RF Input match.

The HMC376LP3 & HMC376LP3E share the same

package and pinout with the HMC382LP3 1.7 - 2.2

GHz LNA. The HMC376LP3 & HMC376LP3E feature

an externally adjustable supply current which allows

the designer to tailor the linearity performance of the

LNA for each application.

Noise Figure: 0.7 dB

Output IP3: +36 dBm

Gain: 15 dB

Externally Adjustable Supply Current

Single Positive Supply: +5.0V

50 Ohm Matched Input/Output

Typical Applications

The HMC376LP3 / HMC376LP3E is ideal for:

• Cellular/3G Infrastructure

• Base Stations & Repeaters

• CDMA, W-CDMA, & TD-SCDMA

• Private Land Mobile Radio

• GSM/GPRS & EDGE

• UHF Reallocation Applications
