GaAs PHEMT MMIC

LOW NOISE AMPLIFIER, 1.7 - 2.2 GHz

v01.0610

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 +5V. The HMC382LP3 & HMC382LP3E feature an

externally adjustable supply current which allows the

designer to tailor the linearity performance of the LNA

for each application. For applications which require

improved noise figure, please see the HMC618LP3(E).

Noise Figure: 1 dB

Output IP3: +30 dBm

Gain: 17 dB

Externally Adjustable Supply Current

Single Positive Supply: +5V

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
