HMC668LP3 / 668LP3E v03.0610 Amplifiers - Low Noise - SMT 7 GaAs PHEMT MMIC LNA w/ FAILSAFE BYPASS MODE, 700 - 1200 MHz Typical Applications Features The HMC668LP3(E) is ideal for: Noise Figure: 0.9 dB • Cellular/3G and LTE/WiMAX/4G Output IP3: +33 dBm • BTS & Infrastructure Gain: 16 dB • Repeaters and Femtocells Failsafe Operation: Bypass is enabled when LNA is unpowered • Tower Mounted Amplifiers Single Supply: +3V or +5V • Test & Measurement Equipment 16 Lead 3x3mm QFN Package: 9 mm 2 Functional Diagram 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 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).
