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 final 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.
