Functional Diagram
General Description
The HMC374 & HMC374E are general purpose broad
band Low Noise Amplifiers (LNA) for use in the 0.3 -
3 GHz frequency range. The LNA provides 15 dB of
gain and a 1.5 dB noise figure from a single positive
supply of +2.75 to +5.5V. The low noise figure coupled
with a high P1dB (22 dBm) and high OIP3 (37 dBm)
make this part ideal for cellular applications. The
compact LNA design utilizes on-chip matching for
repeatable gain and noise figure performance. To
minimize board area the design is offered in a low cost
SOT26 package that occupies only 0.118” x 0.118”.
