The HMC832A is a 3.3 V, high performance, wideband, fractional-N, phase-locked loop (PLL) that features an integrated voltage controlled oscillator (VCO) with a fundamental frequency of 1500 MHz to 3000 MHz and an integrated VCO output divider (divide by 1, 2, 4, 6, ? 62) that enables the HMC832A to generate continuous frequencies from 25 MHz to 3000 MHz. The integrated phase detector (PD) and ?-? modulator, capable of operating at up to 100 MHz, permit wider loop bandwidths and faster frequency tuning with excellent spectral performance.Industry leading phase noise and spurious performance, across all frequencies, enable the HMC832A to minimize blocker effects, and to improve receiver sensitivity and transmitter spectral purity. A low noise floor (?160 dBc/Hz) eliminates any contribution to modulator/mixer noise floor in transmitter applications.The HMC832A is footprint compatible to the market leading HMC830 PLL with an integrated VCO. It features 3.3 V supply and an innovative programmable performance technology that enables the HMC832A to tailor current consumption and corresponding noise floor performance to individual applications by selecting either a low current consumption mode or a high performance mode for an improved noise floor performance.Additional features of the HMC832A include 12 dB of RF output gain control in 1 dB steps; an output mute function to automatically mute the output during frequency changes when the device is not locked; selectable output return loss; programmable differential or single-ended outputs, with the ability to select either output in single-ended mode; and a ?-? modulator exact frequency mode that enables users to generate output frequencies with 0 Hz frequency error; and a register configurable 3.3 V or 1.8 V serial port interface (SPI).Applications Cellular infrastructure Microwave radios WiMax, WiFi Communications test equipment CATV equipment DDS replacement Military Tunable reference sources for spurious-free performance

The LT5528 is a direct I/Q modulator designed for high performance wireless applications, including wireless infrastructure. It allows direct modulation of an RF signal using differential baseband I and Q signals. It supports PHS, GSM, EDGE, TD-SCDMA, CDMA, CDMA2000, W-CDMA and other systems. It may also be con? gured as an image reject up-converting mixer, by applying 90? phase-shifted signals to the I and Q inputs. The I/Q baseband inputs consist of voltage-to-current converters that in turn drive double-balanced mixers. The outputs of these mixers are summed and applied to an on-chip RF transformer, which converts the differential mixer signals to a 50? single-ended output. The four balanced I and Q baseband input ports are intended for DC coupling from a? source with a common-mode voltage level of about 0.5V. The LO path consists of an LO buffer with single-ended input, and precision quadrature generators that produce the LO drive for the mixers. The supply voltage range is 4.5V to 5.25V.Applications Infrastructure Tx for DCS, PCS and UMTS Bands Image Reject Up-Converters for PCS and UMTS Bands Low-Noise Variable Phase-Shifter for 1.5GHz to 2.4GHz Local Oscillator Signals
