General Description
The HMC668LP3(E) is a versatile, high dynamic range
GaAs MMIC Low Noise Amplifier that integrates a low
loss LNA bypass mode on the IC. The amplifier is ide-
al for receivers and LNA modules operating between
0.7 and 1.2 GHz and provides 0.9 dB noise figure,
16 dB of gain and +33 dBm IP3 from a single supply
of +5V @ 57mA. Input and output return losses are
excellent and no external matching components are
required. A single control line is used to switch be-
tween LNA mode and a low loss bypass mode. The
failsafe topology enables the LNA bypass path, when
no DC power is available. The HMC668LP3(E) offers
improved noise figure versus the previously released
HMC373LP3(E).
