The HMC769LP6CE is a fully functioned Fractional-N Phase-Locked-Loop (PLL) Frequency Synthesizer with an integrated Voltage Controlled Oscillator (VCO). The input reference frequency range is DC to 350 MHz while the advanced delta-sigma modulator design in the fractional synthesizer 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. In addition, the HMC769LP6CE offers frequency sweep and modulation features, external triggering, double-buffering, exact frequency control, phase modulation and more. The HMC769LP6CE is packaged in a leadless QFN 6 x 6 mm surface mount package.For theory of operation and register map refer to the "PLLs w/ Integrated VCO - Microwave VCOs" Operating Guide.ApplicationsVSAT RadioMicrowave Point-To-Point RadiosTest Equipment & Industrial ControlMilitary End-UsePhased Array ApplicationsFMCW Radar Systems

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.ApplicationsCellular / PCS / 3GFixed Wireless & WLANCATV, Cable Modem & DBSMicrowave Radio & Test EquipmentIF & RF Applications

The HMC772LC4 is a GaAs MMIC HEMT Low Noise Wideband Amplifier which operates between 2 and 12 GHz. The amplifier provides 15 dB of gain, 1.8 dB noise figure up to 12 GHz and output IP3 of +25 dBm, while requiring only 45 mA from a +4V supply voltage. The Psat output power of up to +15 dBm enables the LNA to function as a LO driver for many of Hittite's balanced, I/Q or image reject mixers. The HMC772LC4 also features I/Os that are DC blocked and internally matched to 50 Ohms, making it ideal for SMT based high capacity microwave radio applications. The HMC772LC4 is housed in a RoHS compliant 4x4 mm QFN leadless ceramic package.ApplicationsWideband Communication SystemsSurveillance SystemsPoint-to-Point RadioPoint-to-Multi-Point RadiosMilitary & SpaceTest Instrumentation

The HMC773 devices are general purpose double-balanced mixers available in a chip (HMC773) and a leadless RoHS compliant SMT package (HMC773LC3B), both of which can be used as an upconverter or downconverter between 6 GHz and 26 GHz. These mixers require no external components or matching circuitry. The HMC773 devices provide excellent LO to RF and LO to IF suppression due to optimized balun structures. The mixers operate with LO drive levels greater than 13 dBm. The HMC773 wideband mixer exhibits consistent conversion gain and compression across its bandwidth. The HMC773LC3B eliminates the need for wire bonding, allowing use of surface mount manufacturing techniques.ApplicationsPoint-to-point radiosPoint-to-multipoint radiosVery small aperture terminal (VSAT)Test equipment and sensorsMilitary end use

The HMC7748 is a multistage power amplifier (PA) that provides 25 W of saturated output power across the band of 2 GHz to 6 GHz. It draws 0.7 A from a 12 V supply and up to 4 A from a 28 V supply. Input signals of as much as −8 dBm are acceptable, and the module has small signal gain of 60 dB.The 12 V supply is regulated internally and generates the negative voltage required for the gate bias. Built-in bias sequencing prevents the drain voltages for the amplifier stages from being applied without the negative voltage present, which protects the amplifiers if 28 V is applied without 12 V supply applied.An external enable pin causes the module to remain in shutdown mode unless the pin is pulled to ground. This pin provides a means of turning the amplifiers off and on without cycling the power supplies.ApplicationsTelecom infrastructureTest instrumentationMilitary
