General Description
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.

The circuit board used in the application should use
RF circuit design techniques. Signal lines should
have 50 Ohm impedance while the package ground
leads should be connected directly to the ground
plane similar to that shown above. A sufficient
number of via holes should be used to connect
the top and bottom ground planes. The evaluation
circuit board shown is available from Hittite upon
request.
