The HMC474 devices are general-purpose SiGe, Heterojunction Bipolar transistor (HBT), gain block MMIC, SMT amplifiers covering dc to 6 GHz. These amplifiers can be used as cascadable 50 Ω RF/IF gain stages with up to 10 dBm output power. The HMC474 devices offer 15 dB or 15.5 dB of gain with 20 dBm or 22 dBm output IP3 at 850 MHz while requiring only 25 mA from a single positive supply. The Darlington topology results in reduced sensitivity to normal process variations and excellent gain stability over temperature while requiring a minimal number of external bias components.Applications Cellular/PCS/3G WiBro/WiMAX/4G Fixed wireless and WLAN CATV, cable modem, and direct broadcast (DBS) Microwave radio and test equipment

The HMC764LP6CE is a fully functioned Fractional-N Phase-Locked-Loop (PLL) with an Integrated Voltage Controlled Oscillator (VCO). The input reference frequency range is 100 kHz to 220 MHz while the advanced delta-sigma modulator design in the fractional PLL allows both ultra-fine step sizes and very low spurious products. The highly integrated structure provides excellent phase noise performance over temperature, shock and process. The HMC764LP6CE is packaged in a leadless QFN 6 x 6 mm surface mount package. The output power is 15 dBm typical, making the HMC764LP6CE ideal for driving the LO port of many of Hittite’s Hi Linearity and I/Q mixer products.For theory of operation and register map refer to the 'PLLs w/ Integrated VCO - Microwave VCOs' Operating Guide.Applications VSAT Radio Point-to-Point / Multi-Point Radio Test Equipment & Industrial Control Military End-Use Phased Array Applications

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 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. Evaluation PCBs are all available with either SMA (50Ω) or Type F (75Ω) connectors.Applications Cellular / PCS / 3G Fixed Wireless & WLAN CATV, Cable Modem & DBS Microwave Radio & Test Equipment IF & RF Applications
