The HMC1048ALC3B is a general-purpose, monolithic microwave integrated circuit (MMIC), double balanced mixer that can be used as a downconverter with dc to 4 GHz at the intermediate frequency (IF) port and 2.25 GHz to 18 GHz at the radio frequency (RF) port. The mixer requires no external components or matching circuitry.The HMC1048ALC3B provides excellent local oscillator (LO) to RF, LO to IF, and RF to IF isolation. The mixer operates with LO drive levels from 9 dBm to 17 dBm. The HMC1048ALC3B eliminates the need for wire bonding and allows the use of surface-mount manufacturing techniques.APPLICATIONSKa band transpondersPoint to multipoint radios and very small aperture terminal (VSAT)Test equipment and sensorsMilitary end use

The HMC1049 is a GaAs MMIC low noise amplifier (LNA) that operates between 0.3 GHz and 20 GHz. This LNA provides 16 dB of small signal gain, a 1.7 dB noise figure, and an Output IP3 of 27 dBm, requiring only 70 mA from a 7 V supply. The P1dB output power of 16 dBm enables the LNA to function as a local oscillator (LO) driver for balanced, I/Q or image rejection mixers. VDDcan be applied to Pad 2 with VDD= 7 V or to Pad 4 with VDD= 4 V. Pad 4 requires a bias tee. The HMC1049 is also internally matched to 50 Ω for ease of integration into multichip modules (MCMs). All data is taken with the chip in a 50 Ω test fixture connected via 0.025 mm (1 mil) diameter wire bonds of 0.31 mm (12 mil) length.ApplicationsPoint-to-point radiosPoint-to-multipoint radiosMilitary and spaceTest instrumentation

The HMC1049LP5E is a GaAs MMIC low noise amplifier (LNA) that operates between 0.3 GHz and 20 GHz. This LNA provides 15 dB of small signal gain, 1.8 dB noise figure, and an IP3 output of 29 dBm, yet requires only 70 mA from a 7 V supply. The P1dB output power of 14.5 dBm enables the LNA to function as a local oscillator (LO) driver for balanced, I/Q, or image rejection mixers. VDDcan also be applied to Pin 21, although Pin 21 requires a bias tee with VDD= 4 V. The HMC1049LP5E amplifier I/Os are internally matched to 50 Ω, and the device is supplied in a compact, leadless 5 mm × 5 mm LFCSP package.ApplicationsTest instrumentationHigh linearity microwave radiosVSAT and SATCOMMilitary and space

The HMC1058 is a sub-harmonically pumped MMIC mixer. It can be used as an upconverter or a downconverter, with DC to 12 GHz at the IF port and 71 to 86 GHz at the RF port. This passive MMIC mixer is fabricated with GaAs Shottky diode technology. All bond pads and the die backside are Ti/Au metallized and the Shottky devices are fully passivated for reliable operation. All data shown herein is measured with the chip in a 50 Ohm environment and contacted with RF probes.APPLICATIONSE-Band Communications SystemsTest Equipment & SensorsMilitary End UseAutomotive Radar

The HMC1060LP3E is a BiCMOS ultra low noise quad-output linear voltage regulator targeted at high performance applications requiring superb power supply isolation.Maximum 500 mA of current, distributed between four independent outputs, enable the HMC1060LP3E to supply all of the power needs of Hittite's Wideband PLL with Integrated VCO products, such as the HMC830LP6GE.Although targeted at Hittite's Wideband PLLs with Integrated VCO products, the HMC1060LP3E makes an excellent general purpose regulator that supports adjustable output voltages ranging anywhere from 1.8V to 5.2V.An Integrated PTAT (Proportional To Absolute Temperature) feature enabled via an external pin, allows the HMC1060LP3E to scale the supply voltage with temperature in order to maximize phase noise and output power performance of Hittite's Wideband with Integrated VCO products, as well as other devices powered by the HMC1060LP3E.Integrated thermal protection disables the outputs of the HMC1060LP3E at extreme temperatures, until the device cools down, making the HMC1060LP3E a robust device capable of dealing with temporary and unforeseen scenarios including momentary short circuits and extreme temperatures.External Enable input provides a convenient way to power on or off all of the devices supplied by the HMC1060LP3E.The HMC1060LP3E is housed in a 3 × 3 mm QFN SMT package.APPLICATIONSUltra Low Noise Frequency Generation (PLLs, VCOs, PLLs with Integrated VCOs)RF & Mixed-Signal Supply
