General Description
The HMC372LP3 is a GaAs PHEMT MMIC Low
Noise Ampli鏗乪r that is ideal for GSM & CDMA
cellular basestation front-end receivers operating
between 700 and 1000 MHz. The ampli鏗乪r has
been optimized to provide 1.0 dB noise 鏗乬ure, 15
dB gain and +34 dBm output IP3 from a single
supply of +5.0V @ 100 mA. Input and output return
losses are 25 and 14 dB respectively with the LNA
requiring only four external components to optimize
the RF Input match, RF ground and DC bias. The
HMC372LP3 shares the same package and pinout
with the HMC356LP3 high IP3 LNA. A low cost,
leadless 3x3 mm (LP3) SMT QFN package houses
the low noise ampli鏗乪r.
