General Description
The HMC286 is a low cost Low Noise Ampli鏗乪r (LNA)
for 2.3 to 2.5 GHz spread spectrum applications. The
LNA provides 19 dB of gain and a 1.7 dB noise 鏗乬ure
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
鏗乬ure 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鈥?x 0.118鈥? which
makes it a small fully integrated solution that can be
easily implemented with other 2.4 GHz ASICs.
