HMC983LP5E is a fractional frequency divider targeted for fractional-N frequency synthesis, and stand-alone low noise frequency divider applications that require exceptional spurious performance.Although the HMC983LP5E can work with any VCO and/or compatible Phase Detector, best performance and features will be achieved when paired with the companion part, the HMC984LP4E.Fabricated in SiGe BiCMOS process, the HMC983LP5E features a 48-bit Delta Sigma Fractional Modulator (DSM) with programmable phase accumulator size, enabling precise control of frequency step size and resolution. Integrated DSM can generate frequencies with nearly 0 Hz frequency error. The DSM also includes a built-in programmable frequency sweep capability, with various automatic and user defined sweep modes and triggering options, including hardware trigger pin, or SPI trigger with optional delayed trigger.HMC983LP5E is a versatile part capable of various configurations. It has 5 general purpose I/Os (GPIOs). DSM outputs are made available from the GPIO port, enabling the HMC983LP5E to import and/or export DSM sequences for various configuration options.HMC983LP5E divider outputs are differential, open collector with programmable current to accommodate different off-chip loads.ApplicationsTest EquipmentPortable InstrumentsHigh Performance Fractional-N Frequency Synthesizerswith Ultra Low SpuriousStand-Alone Divider and/or Delta-Sigma Modulator

The HMC985 devices are absorptive, voltage variable attenuators (VVAs) which operate from 10 GHz to 40 GHz or 20 GHz to 50 GHz and are ideal in designs when an analog dc control signal must be used to control RF signal levels over a 35 dB dynamic range. They feature two shunt-type attenuators which are controlled by two analog voltages, VCTRL1 and VCTRL2. Optimum linearity performance of the attenuators is achieved by first varying VCTRL1 of the first attenuation stage from −3 V to 0 V with VCTRL2 fixed at −3 V. The control voltage of the second attenuation stage, VCTRL2, should then be varied from −3 V to 0 V with VCTRL1 fixed at 0 V. However, if the VCTRL1 and VCTRL2 pins are connected together, it is possible to achieve the full analog attenuation range with only a small degradation in input IP3 performance. Applications include AGC circuits and temperature compensation of multiple gain stages in microwave, point-to-point, and VSAT radios.ApplicationsPoint-to-point radiosVSAT radioTest instrumentationMicrowave sensorsMilitary, ECM, and radar

The HMC986A is a reflective, single-pole, double throw (SPDT) switch, manufactured using a gallium arsenide (GaAs) process. This switch typically provides low insertion loss of 2.3 dB and high isolation of 30 dB in broadband frequency range from 0.1 GHz to 50 GHz.This switch operates with two negative logic control voltages from −5 V to −3 V. All electrical performance data is acquired with the RFx pads of the HMC986A connected to 50 Ω transmission lines via one 3.0 mil × 0.5 mil ribbon bond of minimal length.ApplicationsTest instrumentationMicrowave radios and very small aperture terminals (VSATs)Military radios, radars, and electronic counter measures (ECMs)Broadband telecommunications systems
