General Description
The HMC373LP3 / HMC373LP3E are versatile, high
dynamic range GaAs MMIC Low Noise Amplifiers
that integrates a low loss LNA bypass mode on the
IC. The amplifier is ideal for GSM & CDMA cellular
basestation front-end receivers operating between
700 and 1000 MHz and provides 0.9 dB noise figure,
14 dB of gain and +35 dBm IP3 from a single supply of
+5.0V @ 90 mA. Input and output return losses are 28
and 12 dB respectively with the LNA requiring minimal
external components to optimize the RF input match,
RF ground and DC bias. By presenting an open or
short circuit to a single control line, the LNA can be
switched into a low 2.0 dB loss bypass mode reducing
the current consumption to 10 μA. A low cost, leadless
3x3 mm QFN surface mount package (LP3) houses
the low noise amplifier.
