HMC286

GaAs MMIC LOW NOISE

AMPLIFIER, 2.3 - 2.5 GHz

v02.0204

General Description

Features

Functional Diagram

2.4 GHz LNA

Noise Figure: 1.7 dB

Gain: 19 dB

Single Supply: +3V

No External Components

Ultra Small SOT26 Package

Typical Applications

The HMC286 is ideal for:

• BlueTooth

• Home RF

• 802.11 WLAN Radios

• PCMCIA Platforms

The HMC286 is a low cost Low Noise Amplifier (LNA)

for 2.3 to 2.5 GHz spread spectrum applications. The

LNA provides 19 dB of gain and a 1.7 dB noise figure

from a single positive +3V power supply that consumes

only 8.5mA. The typical output 1 dB compression point

is +6 dBm at 2.4 GHz. The compact LNA design uti-

lizes on-chip matching for repeatable gain and noise

figure performance. In addition, eliminating the external

matching circuitry also reduces the overall size of the

LNA function. The HMC286 was designed to meet the

size constraints of PCMCIA platforms and uses the

SOT26 package that occupies 0.118” x 0.118”, which

makes it a small fully integrated solution that can be

easily implemented with other 2.4 GHz ASICs.
