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 / HMC286E is ideal for:

• BlueTooth

• Home RF

• 802.11 WLAN Radios

• PCMCIA Platforms

The HMC286 & HMC286E are low cost Low Noise

Amplifiers (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 utilizes 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 & HMC286E were designed to meet the

size constraints of PCMCIA platforms and uses the

SOT26 package that occupies 0.118” x 0.118”, which

makes them a small fully integrated solution that can

be easily implemented with other 2.4 GHz ASICs.
