General Description
The HMC375LP3 & HMC375LP3E high dynamic
range GaAs PHEMT MMIC Low Noise Amplifiers are
ideal for GSM & CDMA cellular basestation front-end
receivers operating between 1.7 and 2.2 GHz. This
LNA has been optimized to provide 0.9 dB noise
figure, 17 dB gain and +33 dBm output IP3 from a
single supply of +5.0V @ 136mA. Input and output
return losses are 14 dB typical with the LNA requiring
minimal external components to optimize the RF input
match, RF ground and DC bias. The HMC375LP3
& HMC375LP3E share the same package with the
HMC356LP3 and HMC372LP3 high IP3 LNAs. A
low cost, leadless 3x3 mm (LP3) SMT QFN package
houses the low noise amplifier.
