The HMC875LC3C is a SiGe monolithic, ultra fast comparator which features reduced swing CML output drivers and clock inputs. The comparator supports 20 Gbps operation while providing 120 ps clock to data output delay and 60 ps minimum pulse width with 0.2 ps rms random jitter (RJ). 25 Gbps operation can be achieved with reduced output voltage swing. Overdrive and slew rate dispersion are typically 10 ps, making the device ideal for a wide range of applications from ATE to broadband communications. The reduced swing CML output stage is designed to directly drive 400 mV into 50 Ohms terminated to GND. The HMC875LC3C features high speed latches with programmable hysteresis, and is configured to operate as a clocked comparator.ApplicationsATE ApplicationsHigh Speed InstrumentationDigital Receiver SystemsPulse SpectroscopyHigh Speed Trigger CircuitsClock & Data Restoration

The HMC877LC3 is a phase shifter/time delay with 0 to 500°(1.4 UI) continuously adjustable shift/delay range. The delay control is linearly monotonic with respect to the differential control voltage (VDCP, VDCN) and the control input has a modulation bandwidth of 2.5 GHz. The device provides a differential output voltage with constant amplitude for single-ended or differential input voltages above the input sensitivity level, while the output voltage swing may be adjusted using the VAC control pin. The HMC877LC3 features internal temperature compensation and bias circuitry to minimize delay variations with temperature. The device also features a delay control voltage range adjustment pin, LC. All RF input and outputs of the HMC877LC3 are internally terminated with 50 Ohms to VCC, and may either be AC or DC coupled. Output pins can be connected directly to a 50 Ohm to VCCterminated system, while DC blocking capacitors must be used if the terminated system input is 50 Ohms to a DC voltage other than VCC. The HMC877LC3 is available in ROHS-compliant 3 x 3 mm SMT package.APPLICATIONSSynchronization of Clock & DataTransponder DesignBroadband Test & MeasurementRF ATE Applications

The HMC881A is a monolithic microwave integrated circuit (MMIC) low-pass filter that features a user-selectable cutoff frequency. The cutoff frequency can be varied from 2.4 GHz to 4 GHz by applying a single analog tuning voltage between 0 V and 14 V. This low-pass filter provides a low 3 dB insertion loss, 16.5 dB return loss, and 1.35 × f3dBstopband attenuation of >20 dB. This tunable filter can be used as a much smaller alternative to physically large switched filter banks and cavity tuned filters. The HMC881A has excellent microphonics due to the monolithic design, and provides a dynamically adjustable solution in advanced communications applications. The low-pass tunable filter is packaged in a RoHS compliant 5 mm × 5 mm LFCSP package.ApplicationsTesting and measurement equipmentMilitary radar and electronic warfare/electronic countermeasures (ECMs)Satellite communication and spaceIndustrial and medical equipment
