The ADF41020 frequency synthesizer can be used to implement local oscillators as high as 18 GHz in the up conversion and down conversion sections of wireless receivers and transmitters. It consists of a low noise, digital phase frequency detector (PFD), a precision charge pump, a programmable reference divider, and high frequency programmable feedback dividers (A, B, and P). A complete phase-locked loop (PLL) can be implemented if the synthesizer is used with an external loop filter and voltage controlled oscillator (VCO). The synthesizer can be used to drive external microwave VCOs via an active loop filter. Its very high bandwidth means a frequency doubler stage can be eliminated, simplifying system architecture and reducing cost. The ADF41020 is software-compatible with the existing ADF4106/ADF4107/ADF4108 family of devices from Analog Devices, Inc. Their pinouts match very closely with the exception of the ADF41020’s single-ended RF input pin, meaning only a minor layout change is required when updating current designs.Applications Microwave point-to-point/multipoint radios Wireless infrastructure VSAT radios Test equipment Instrumentation

The HMC513LP5(E) is a GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC VCOs. The HMC513LP5(E) integrates resonators, negative resistance devices, varactor diodes and feature half frequency and divide-by- 4 outputs. The VCO’s phase noise performance is excellent over temperature, shock, and process due to the oscillator’s monolithic structure. Power output is +7 dBm typical from a +3V supply voltage. The prescaler function can be disabled to conserve current if not required. The voltage controlled oscillator is packaged in a leadless QFN 5×5 mm surface mount package, and requires no external matching components.APPLICATIONS VSAT Radio Point-to-Point/Multi-Point Radio  Test Equipment & Industrial Controls  Military End-Use

The ADF5000 prescaler is a low noise, low power, fixed RF divider block that can be used to divide down frequencies as high as 18 GHz to a lower frequency suitable for input to a PLL IC, such as the?ADF4156 or the ADF4106. The ADF5000 provides a divide-by-2 function. The ADF5000 operates from a 3.3 V supply and has differential 100 ? RF outputs to allow direct interface to the differential RF inputs of PLLs such as the ADF4156 and ADF4106.Applications PLL frequency range extender Point-to-point radios VSAT radios Communications test equipment?

The HMC833LP6GE is a low noise, wide band, Fractional-N Phase-Locked-Loop (PLL) that features an integrated Voltage Controlled Oscillator (VCO) with a fundamental frequency of 1500 MHz - 3000 MHz, and an integrated VCO Output Divider (divide by 1/2/4/6.../60/62) and doubler, that together allow the HMC833LP6GE to generate frequencies from 25 MHz to 6000 MHz. The integrated Phase Detector (PD) and delta-sigma modulator, capable of operating at up to 100 MHz, permit wider loop-bandwidths with excellent spectral performance.The HMC833LP6GE features industry leading phase noise and spurious performance, across all frequencies, that enable it to minimize blocker effects, and improve receiver sensitivity and transmitter spectral purity. The superior noise floor (< -170 dBc/Hz) makes the HMC833LP6GE an ideal source for a variety of applications - such as; LO for RF mixers, a clock source for high-frequency data-converters, or a tunable reference source for ultra-low spurious applications.Additional features of the HMC833LP6GE include RF output power control from 0 to 9 dB (3 dB steps), output Mute function, and a delta-sigma modulator Exact Frequency Mode which enables users to generate output frequencies with 0 Hz frequency error.Applications Cellular Infrastructure Microwave Radio WiMax, WiFi Communications Test Equipment CATV Equipment DDS Replacement Military Tunable Reference Source for?Spurious- Free Performance

The HMC835LP6GE is a low noise, wide band, Fractional-N PLL that features an integrated VCO with a fundamental frequency of 2020 to 4100 MHz, and an integrated VCO Output Divider (divide by 2/4/6/.../60/62) that together enable the HMC835LP6GE to generate frequencies from 33 MHz to 4100 MHz.
