RF MIXERS/MULTIPLIERS RF IC'S;

The ADF5355 allows implementation of fractional-N or integer-N phase-locked loop (PLL) frequency synthesizers when used with an external loop filter and an external reference frequency. The wideband microwave VCO design permits frequency operation from 6.8 GHz to 13.6 GHz at one radio frequency (RF) output. A series of frequency dividers at another frequency output permits operation from 54 MHz to 6800 MHz.The ADF5355 has an integrated VCO with a fundamental output frequency ranging from 3400 MHz to 6800 MHz. In addition, the VCO frequency is connected to divide by 1, 2, 4, 8, 16, 32, or 64 circuits that allow the user to generate RF output frequencies as low as 54 MHz. For applications that require isolation, the RF output stage can be muted. The mute function is both pin and software controllable.Control of all on-chip registers is through a simple 3-wire interface. The ADF5355 operates with analog and digital power supplies ranging from 3.15 V to 3.45 V, with charge pump and VCO supplies from 4.75 V to 5.25 V. The ADF5355 also contains hardware and software power-down modes.Applications Wireless infrastructure (W-CDMA, TD-SCDMA, WiMAX, GSM, PCS, DCS, DECT) Point to point/point to multipoint microwave links Satellites/VSATs Test equipment/instrumentation Clock generation

The HMC478 devices are SiGe, heterojunction bipolar transistor (HBT), gain block MMIC, SMT amplifiers covering dc to 4 GHz. These amplifiers can be used as cascadable 50 Ω RF/IF gain stages as well as LO or PA drivers with up to 17 dBm or 20 dBm output power. These amplifiers offer 22 dB or 23 dB of gain with 31 dBm, 32 dBm, or 33 dBm output IP3 at 850 MHz, while requiring only 62 mA from a single positive supply. The Darlington feedback topology results in reduced sensitivity to normal process variations and excellent gain stability over temperature while requiring a minimal number of external bias components.Applications Cellular/PCS/3G/4G Fixed wireless and WLAN CATV, cable modem, and direct broadcast satellite (DBS) Microwave radio and test equipment 

The HMC368LP4(E) is a miniature amp-doubler-amps utilizing GaAs PHEMT technology in 4 ? 4 mm leadless surface mount package. When driven by a +2 dBm signal, the multiplier provides +15 dBm typical output power from 9 to 16 GHz. The Fo and the 3Fo isolations are 18 dB typical. The low additive SSB phase noise of ?140 dBc/Hz at 100 kHz offset helps the user maintain good system noise performance. The HMC368LP4(E) is ideal for use in LO multiplier chains allowing reduced parts count vs. traditional approaches.APPLICATIONS Microwave Radios & VSAT Fiber Optic Infrastructure Military Communications & Radar
