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). Noise figure: 0.9 dB output ip3: +33 dBm Gain: 16 dB failsafe operation: Bypass is enabled when lNA is unpowered single supply: +3V or +5V 16 lead 3x3mm QfN package: 9 mm2 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 Electrical Specifications, T A = +25° C, Rbias = 0 Ohm parameter lNA mode Bypass mode failsafe mode Units Vdd = +3V Vdd = +5V min.
