The HMC997LC4 is a GaAs MMIC PHEMT analog variable gain amplifier and/or driver amplifier which operates between 17 and 27 GHz. Ideal for microwave radio applications, the amplifier provides up to 20.5 dB of gain, output P1dB of up to +24 dBm, and up to +31 dBm of output IP3 at maximum gain, while requiring only 170 mA from a +5V supply. A gain control voltage (Vctrl) is provided to allow variable gain control up to 15 dB. Gain flatness is excellent making the HMC997LC4 ideal for EW, ECM and radar applications. The HMC997LC4 is housed in a RoHS compliant 4 × 4 mm ceramic QFN leadless package and is compatible with high volume surface mount manufacturing.ApplicationsPoint-to-Point RadioPoint-to-Multi-Point RadioEW & ECM SubsystemsKa-Band RadarTest Equipment

The HMC998A is a GaAs MMIC pHEMT Distributed Power Amplifier die which operates between DC and 22 GHz. The amplifier provides 14.5 dB of gain, 43 dBm output IP3 and +32.5 dBm of output power at 1 dB gain compression while requiring 500 mA quiescent current from a +15 V supply. The HMC998A exhibits a slightly positive gain slope, making it ideal for EW, ECM, Radar and test equipment applications. The HMC998A amplifier I/Os are internally matched to 50 Ohms facilitating integration into Mutli-Chip-Modules (MCMs). All data is taken with the chip connected via two 0.025 mm (1 mil) wire bonds of minimal length 0.31 mm (12 mils).ApplicationsTest InstrumentationMicrowave Radio & VSATMilitary & SpaceTelecom InfrastructureFiber Optics

The HMCAD1512 is a versatile high performance low power analog-to-digital converter (ADC), utilizing time-interleaving to increase sampling rate. Integrated Cross Point Switches activate the input selected by the user.The device contains 2 ADCs that can be interleaved by the user to act as a single channel or two channels. In single channel mode, either of the two inputs can be selected as a valid input to the single ADC channel. In dual channel mode, either of the two inputs can be selected for each ADC channel. (The HMCAD1512 does not support the quad-channel mode. The HMCAD1511 should be used for this purpose).An internal, low jitter and programmable clock divider makes it possible to use a single clock source for all operational modes.The HMCAD1512 is based on a proprietary structure, and employs internal reference circuitry, a serial control interface and serial LVDS/RSDS output data. Data and frame synchronization clocks are supplied for data capture at the receiver. Internal 1 to 50× digital coarse gain with ENOB > 7.5 up to 16× gain, allows digital implementation of oscilloscope gain settings. Internal digital fine gain can be set separately for each ADC to calibrate for gain errors.Various modes and configuration settings can be applied to the ADC through the serial control interface (SPI). Each channel can be powered down independently and data format can be selected through this interface. A full chip idle mode can be set by a single external pin. Register settings determine the exact function of this pin.HMCAD1512 is designed to easily interface with Field Programmable Gate Arrays (FPGAs) from several vendors.APPLICATIONSPoint-to-point Microwave LinksDigital OscilloscopesSatellite Receivers

The HMCAD1520 is a versatile high performance low power analog-to-digital converter (ADC), with interleaving High Speed Modes to increase sampling rate. Integrated Cross Point Switches activate the input selected by the user.In Single Channel Mode, one of the four inputs can be selected as valid input to the single ADC channel. In Dual Channel Mode, any two of the four inputs can be selected to each ADC channel. In Quad Channel Mode and Precision Mode, any input can be assigned to any ADC channel. An internal, low jitter and programmable clock divider makes it possible to use a single clock source for all operational modes.The HMCAD1520 is based on a proprietary structure, and employs internal reference circuitry, a serial control interface and a serial LVDS output data.
