Product Details

The ADF4150HV is a 3.0 GHz, fractional-N or integer-N frequency synthesizer with an integrated high voltage charge pump. The synthesizer can be used to drive external wideband VCOs directly, eliminating the need for operational amplifiers to achieve higher tuning voltages. This simplifies design and reduces cost while improving phase noise, in contrast to active filter topologies, which tend to degrade phase noise compared to passive filter topologies.

The VCO frequency can be divided by 1, 2, 4, 8, or 16 to allow the user to generate RF output frequencies as low as 31.25 MHz. For applications that require isolation, the RF output stage can be muted. The mute function is both pin- and software-controllable.

A simple 3-wire interface controls all on-chip registers. The charge pump operates from a power supply ranging from 6 V to 30 V, whereas the rest of the device operates from 3.0 V to 3.6 V. The ADF4150HV can be powered down when not in use.

Design Tools


ADIsimPLL enables the rapid and reliable evaluation of new high performance PLL products from ADI. It is the most comprehensive PLL Synthesizer design and simulation tool available today. Simulations performed include all key non-linear effects that are significant in affecting PLL performance. ADIsimPLL removes at least one iteration from the design process, thereby speeding the design- to-market.


ADIsimRF is an easy-to-use RF signal chain calculator. Cascaded gain, noise, distortion and power consumption can be calculated, plotted and exported for signal chains with up to 50 stages. ADIsimRF also includes an extensive data base of device models for ADI’s RF and mixed signal components.
