The HMC760LC4B is a SiGe monolithic, fully differential, single rank, track-and-hold (T/H) that provides unprecedented bandwidth and dynamic-range performance to wideband sampled signal systems. The T/H offers precision signal sampling over 5 GHz bandwidth, with 9 to 10-bit linearity from DC to 5 GHz input frequency, 0.9 mV noise, and <70 fs random aperture jitter. The device can be clocked to 4 GS/s with minimal dynamic range loss. The T/H can be used to expand the bandwidth and/or high-frequency linearity of high-speed A/D conversion and signal acquisition systems.APPLICATIONSRF ATE ApplicationsDigital Sampling OscilloscopesRF Demodulation SystemsDigital Receiver SystemsHigh Speed Peak DetectorsSoftware Defined RadioRadar, ECM & ELINT SystemsHigh Speed DAC De-Glitching

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 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 HMC775LC5 is a compact I/Q MMIC mixer in a leadless ceramic SMT package, which can be used as either an Image Reject Mixer or a Single Sideband Upconverter. The mixer utilizes two standard Hittite double balanced mixer cells and a 90 degree hybrid fabricated in a GaAs MESFET process. A low frequency quadrature hybrid was used to produce a 1 GHz USB IF output. This product is a much smaller alternative to hybrid style Image Reject Mixers and Single Sideband Upconverter assemblies. The HMC775LC5 eliminates the need for wire bonding and allows the use of surface mount manufacturing techniques.ApplicationsPoint-to-Point and Point-to-Multi-Point RadioDigital RadioVSATMilitary & Space

The HMC783LP6CE is a fully functioned Fractional-N Phase-Locked-Loop (PLL) with an Integrated Voltage Controlled Oscillator (VCO).
