ADF4356 Wideband Synthesizer feature RF output mute function.

Press Release Summary:

Suitable for wireless infrastructure, microwave point-to-point links, electronic test and measurement, and satellite terminals applications, 6.8 GHz ADF4356 Wideband Synthesizer is integrated with VCO that provides an output ranging from 3400 MHz to 6800 MHz. Operating at -40°C to +85°C temperature range with 3.3 V analog and digital power, units deliver phase noise of -113 dBc/Hz at 100 kHz offset at 5 GHz and resolution of 52-bit modulus.

Original Press Release:

Richardson RFPD Introduces New 6.8 GHz Wideband Synthesizer with Integrated VCO from ADI

Suitable for applications such as wireless infrastructure, microwave point-to-point links, electronic test and measurement, and satellite terminals

Richardson RFPD, Inc. announced today the availability and full design support capabilities for a new wideband synthesizer from Analog Devices, Inc.

The ADF4356 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. A series of frequency dividers at another frequency output permits operation from 53.125 MHz to 6800 MHz. The ADF4356 has an integrated VCO with a fundamental output frequency ranging from 3400 MHz to 6800 MHz.

Additional key features of the ADF4356 include:

  • Integer channel: -227 dBc/Hz; Fractional channel: -225 dBc/Hz
  • Integrated RMS jitter (1 kHz to 20 MHz): 97 fs for 6 GHz output
  • High resolution, 52-bit modulus
  • Phase frequency detector (PFD) operation to 125 MHz
  • Reference input frequency operation to 600 MHz
  • Maintains frequency lock over -40°C to +85°C
  • Phase noise: -113 dBc/Hz @ 100 kHz offset at 5 GHz
  • Programmable divide by 1, 2, 4, 8, 16, 32, or 64 output
  • Analog and digital power supplies: 3.3 V
  • Charge pump and VCO power supplies: 5.0 V typical
  • Logic compatibility: 1.8 V
  • Programmable output power level
  • RF output mute function
