The HMC863ALC4 is a three stage GaAs pHEMT MMIC 1/2 Watt Power Amplifier which operates between 24 and 29.5 GHz. The HMC863ALC4 provides 24 dB of gain, +28.5 dBm of saturated output power and 22.5% PAE from a +5.5V supply. High output IP3 makes the HMC863ALC4 ideal for point-to-point and point-to-multi-point radio systems as well as VSAT applications. The RF I/Os are DC blocked and matched to 50 Ohms for ease of integration into higher level assemblies. The HMC863ALC4 can be operated over a Vdd range of +4.0 to +6.0V.ApplicationsPoint-to-point radiosPoint-to-multi-point radiosVSATMilitary & space

The HMC865LC3 is a Limiting Amplifier packaged in a leadless 3x3 mm ceramic surface mount package which supports up to 43 Gbps operation. The amplifier provides 30 dB of differential gain. Output voltage swing is adjustable up to 800 mVP-Pdifferential by using the VAC analog control input. Additive rms jitter is less than 300 fs for 32 Gbps operation. HMC865LC3 has an internal DC offset correction circuit which provides differential 10 mVP-Pinput sensitivity.All input/output RF signals of the HMC865LC3 are terminated with 50 Ohms to +3.3V on chip and may be either AC or DC coupled. The outputs of the device can be operated either differentially or single-ended. Outputs can be connected directly to 50 Ohm terminated system referenced to 3.3V, while DC blocking capacitors may be used if the terminating system is 50 Ohms to a non 3.3V level.APPLICATIONS100 Gbps Ethernet100 Gbps Long Haul40 Gbps (D)QPSK ReceiversBroadband Gain Block for Test & Measurement Equipment

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
