The amplifier is ideal 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 between 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).
