Functional Diagram

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.
