Functional Diagram

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.
