High Voltage, Fractional-N / Integer-N PLL Synthesizer

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.

Applications

  • Wireless infrastructure
  • Microwave point-to-point/point-to-multipoint radios
  • VSAT radios
  • Test equipment
  • Private/land mobile radio

Product Details

The Eval-ADF4150HVEB1Z is a fully populated, 4-layers evaluation board which allows evaluation of the ADF4150HV high voltage, fractional-N PLL synthesizer.

 

The board contains 25 MHz TCXO working as reference signal and a VCO covering octave frequency range from 1 GHz to 2 GHz. VCO output and RF outputs are connected to edge-mounted SMA connectors, which allows easy connection to a spectrum analyzer. For normal operation it requires two external supplies (30 V / 40 mA for VCO and 5 V / 180 mA for the rest of the board).


The ADF4150HV evaluation board software controls the operation of the ADF4150HV evaluation board from a PC over a USB port. The software installation program is available on the CD attached to evaluation kit. The software has to be installed before connecting the board to the PC and it will be available under Programs -> Analog Devices -> ADF4150HV.
