1 7 Typical Applications The HMC668LP3(E) is ideal for: Cellular/3G and LTE/WiMAX/4G BTS & Infrastructure Repeaters and Femtocells Tower Mounted Amplifiers Test & Measurement Equipment Functional Diagram v3.61 FAILSAFE BYPASS MODE, 7-1 MHz Features Noise Figure:.9 db Output IP3: +33 dbm Gain: db Electrical Specifications, T A = +25 C, Rbias = Ohm Failsafe Operation: Bypass is enabled when LNA is unpowered Single Supply: +3V or +5V Lead 3x3mm QFN Package: 9 mm 2 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.7 and 1.2 GHz and provides.9 db noise figure, db of gain and +33 dbm IP3 from a single supply of 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).
