HMC770LP4BE v02.1111 GaAs pHEMT 50 / 75 Ohm DIFFERENTIAL AMPLIFIER, 0.04 - 1 GHz Typical Applications Features High Output IP3: +40 dBm The Hmc 770lp 4Be is ideal for: Single Positive Supply: +5V Cellular / PCS / 3G 1 Low Noise Figure: 2.5 dB Fixed Wireless & WLAN Differential RF I/Os CATV, Cable Modem & DBS 20 Lead 4x4 mm SMT Package: 16mm Microwave Radio & Test Equipment IF & RF Applications General Description Functional Diagram The HMC770LP4BE is a GaAs pHEMT Differential Gain Block MMIC amplifier covering 40 MHz to 1 GHz and packaged in a 4x4 mm plastic QFN SMT package. This versatile amplifier can be used as a cascadable IF or RF gain stage in both 50 Ohm and 75 Ohm applications. The HMC770LP4BE delivers 16 dB gain, and +40 dBm output, with only 2.5 dB m noise figure. Differential I/Os make this amplifier ideal for transimpedance and SAW filter applications, and in transceivers where the IF path must be handled differentially for improved noise performance. c Evaluation PCBs are all available with either SMA (50) or Type F (75) connectors. 2 Electrical Specifications, T = +25 C, Vdd = Vdd1 = Vdd2 = +5V, Rbias = R1 = 200 A Min.
