Wideband Synthesizer With Integrated VCO (62.5Mhz To 32GHz): ADF4371

ADF4371

The ADF4371 from Analog Devices is a Microwave Wideband Synthesizer with Integrated VCO. Most frequently used in the aerospace and defense field, the ADF4371 has an integrated VCO with a fundamental output frequency ranging from 4000 MHz to 8000 MHz.

The ADF4371 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. The wideband microwave voltage controlled oscillator (VCO) design allows frequencies from 62.5 MHz to 32 GHz to be generated.
