GaAs PHEMT MMIC

LOW NOISE AMPLIFIER, 1.7 - 2.2 GHz

v00.1005

General Description

Features

Functional Diagram

The HMC382LP3 & HMC382LP3E high dynamic

range GaAs PHEMT MMIC Low Noise Amplifiers are

ideal for GSM & CDMA cellular basestation front-end

receivers operating between 1.7 and 2.2 GHz. This

LNA has been optimized to provide 1.0 dB noise figure,

17 dB gain and +30 dBm output IP3 from a single

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

13 dB typical and the LNA requires no external mat-

ching components. The HMC382LP3 & HMC382LP3E

share the same package and pinout with the

HMC376LP3 0.7 - 1.0 GHz LNA. The HMC382LP3 &

HMC382LP3E feature an externally adjustable supply

current which allows the designer to tailor the linearity

performance of the LNA for each application.

Noise Figure: 1.0 dB

Output IP3: +30 dBm

Gain: 17 dB

Externally Adjustable Supply Current

Single Positive Supply: +5.0V

50 Ohm Matched Input/Output

Typical Applications

The HMC382LP3 / HMC382LP3E is ideal for:

• Cellular/3G Infrastructure

• Base Stations & Repeaters

• CDMA, W-CDMA, & TD-SCDMA

• GSM/GPRS & EDGE
