Analog Devices

The HMC144 devices are double-balanced MMIC mixers available in a chip (HMC144), a leadless Pb-free SMT package (HMC144LC4), and a hermetic SMT leadless package (HMC144LH5), all of which can be used as an upconverter or downconverter from 6 GHz to 20 Ghz. The HMC144 utilizes a standard 1 μm GaAs metal semiconductor field effect transistor (MESFET) process and is identical to the HMC143, except that the layout is a mirror image designed to ease integration into image reject mixer modules. Broadband operation and excellent isolations are provided by on-chip baluns, which require no external components and no dc bias. The HMC144 devices are more reliable alternatives to hybrid diode mixers, assuring consistent conversion loss and isolation performance over multiple and high volume production lots. The design of the HMC144 is similar to the HMC141 and HMC142 mixers, but with an IF combiner in a double-balanced design, providing improved RF/IF isolation. The HMC144LC4 and HMC144LH5 eliminate the need for wire bonding, allowing use of surface mount manufacturing techniques.ApplicationsMicrowave point-to-point radiosVery small aperture terminal (VSAT)Test equipment and sensorsMilitary end useTelecom infrastructureTest instrumentationMilitary radio, radar, and electronic countermeasure (ECM)Space systems

The HMC158 devices are miniature frequency doublers that are available in a monolithic microwave integrated circuit (MMIC) die (HMC158) and a nonhermetic, ceramic surface mount package (HMC158C8). Suppression of undesired fundamental and higher order harmonics is 40 dB typical with respect to input signal level. The doublers use the same diode/balun technology used in Hittite MMIC mixers, feature small size, and require no dc bias.ApplicationsWireless local loopLocal multipoint distribution systems (LMDS)Very small aperture terminal (VSAT)Point-to-point radiosUnlicensed National Information Infrastructure (U-NII) and high performance radio LAN (HiperLAN)Test equipment

The HMC168C8 is a miniature double-balanced mixer in a non-hermetic ceramic surface mount package that can be used as an upconverter, downconverter or biphase modulator. The device is a passive diode/ balun type mixer with high dynamic range. Noise figure is essentially equal to the conversion loss. The mixer can handle larger signal levels than most active mixers due to the high third order intercept. MMIC implementation provides exceptional balance in the circuit resulting in high LO/RF and LO/IF isolations and unit-to-unit consistency. This mixer has applications where small size and surface mount compatibility are important.ApplicationsMicrowave Point-to-Point Radios5.8 GHz ISM Band Circuits

The HMC174MS8(E) is a low-cost SPDT switches in 8-lead MSOP packages for use in transmit-receive applications which require very low distortion at high signal power levels. The device can control signals from DC to 3 GHz and is especially suited for Cellular/3G & WiMAX applications with only 0.5 dB loss. The design provides exceptional intermodulation performance; providing a +60 dBm third order intercept at 8 Volt bias. RF1 and RF2 are reflective shorts when "OFF".

The HMC187AMS8(E) is a miniature frequency doubler MMIC in plastic an 8-lead MSOP package. The suppression of undesired fundamental and higher order harmonics is 40 dB typical with respect to input signal levels. The doubler uses the same diode/ balun technology used in Hittite MMIC mixers. The doubler is ideal for high volume applications where frequency doubling of a lower frequency is more economical than directly generating a higher frequency. The passive Schottky diode doubler technology contributes no measurable additive phase noise onto the multiplied signal.ApplicationsWireless Local LoopLMDS, VSAT, and Point-to-Point RadiosUNII & HiperLANTest Equipment
