Together with an external loop filter and a voltage controlled crystal oscillator (VCXO), the HMC1031 forms a complete clock generator solution targeted at low frequency jitter attenuation and reference clock generation applications.The HMC1031 features a low power integer N divider, support-ing divide ratios of 1, 5, and 10, which is controlled via external hardware pins and requires no serial port.The integrated phase detector and charge pump are capable of operating at up to 140 MHz, and a maximum VCXO input of 500 MHz ensures frequency compliance with a wide variety of system clocks and VCXOs.Additional features include an integrated lock detect indicator available on a dedicated hardware pin, and a built in power-down mode.The HMC1031 is housed in an 8-lead MSOP package.APPLICATIONSLow jitter clock generationLow bandwidth (BW) jitter attenuationLow frequency phase-locked loops PLLFrequency translationOven controlled crystal oscillator (OCXO) frequency multiplierPhase lock clean high frequency references to 10 MHz equipment

The HMC1032LP6GE is a low-noise, wide-band clock generator IC with a fractional-N Phase Locked Loop (PLL) that features an integrated Voltage Controlled Oscillator (VCO). The device provides differential clock outputs between 125 and 350 MHz range. The HMC1032LP6GE features low noise Phase Detector (PD) and Delta-Sigma modulator, capable of operating at up to 100 MHz, permit wider loop-bandwidths with excellent spectral performance.The HMC1032LP6GE features industry leading phase noise and jitter performance, across the operating range, that enable it to improve link level jitter performance, Bit-Error-Rates (BER) and eye diagram metrics. The superior noise floor (<-165 dBc/Hz) makes the HMC1032LP6GE an ideal source for a variety of applications –such as clock references for high speed data converters, physical layer devices (PHY), serializer/deserializer (SERDES) circuits, FPGAs and processors. The HMC1032LP6GE can also be used as reference clock and LO for 1G/10G Ethernet line cards as well as jitter attenuation and frequency translation.The differential output of the HMC1032LP6GE includes a 2-bit output amplitude control which may be set via the SPI serial programming interface, and an output Mute function. The Delta-Sigma Modulator of the HMC1032LP6GE features Hittite’s Exact Frequency Mode, which enables users to generate output frequencies with close to 0 Hz frequency error.APPLICATIONS1G/10G Ethernet Line CardsOTN & SONET/SDH ApplicationsHigh Frequency Processor ClocksLow Jitter SAW Oscillator ReplacementFiber Channel Interface ClocksCellular/4G InfrastructureDDS Replacement10G Optical Modules, Transponders, Line Cards

The HMC1040CHIPS is a gallium arsenide (GaAs), pseudomorphic high electron mobility transistor (pHEMT), monolithic microwave integrated circuit (MMIC), low noise wideband amplifier that operates from 20 GHz to 44 GHz. The HMC1040CHIPS is self biased and provides a typical gain of 25.0 dB, a 2 dB typical noise figure, and a typical output third-order intercept (IP3) of 25.5 dBm typical, requiring only 65 mA from a 2.5 V supply voltage. The typical saturated output power (PSAT) of 15.5 dBm enables the low noise amplifier (LNA) to function as a local oscillator (LO) driver for many of Analog Devices, Inc., balanced, in phase quadrature (I/Q) or image rejection mixers.The HMC1040CHIPS also feature inputs and outputs that are internally matched to 50 Ω, making it ideal for surface-mounted technology (SMT)-based, high capacity microwave radio applications.ApplicationsSoftware defined radiosElectronic warfareRadar applicationsSatellite communicationElectronic warfareInstrumentationTelecommunications

The HMC1041LC4 is a compact I/Q MMIC mixer in a leadless "Pb free" SMT package, which can be used as either an Image Reject Mixer or a Single Sideband Upconverter. The mixer utilizes two standard Hittite double balanced mixer cells and a 90 degree hybrid fabricated in a GaAs MES FET process. A low frequency quadrature hybrid was used to produce a 1000 MHz USB IF output. This product is a much smaller alternative to hybrid style Image Reject Mixers and Single Sideband Upconverter assemblies. The HMC1041LC4 eliminates the need for wire bonding and allows the use of surface mount manufacturing techniques.ApplicationsPoint-to-Point RadioPoint-to-Multi-Point RadioTest Equipment & 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 HMC1055 is a low cost, gallium arsenide (GaAs), single-pole, single-throw (SPST) switch in a surface-mount LFCSP package. This switch offers low insertion loss, high isolation, and exceptional third-order intermodulation performance that make it ideal for many cellular and wireless infrastructure applications from 0.5 GHz to 4.0 GHz.The HMC1055 operates with single positive supply voltage and a single positive control voltage at very low dc currents.
