Analog Devices ADF4368 microwave wideband synthesiser

Richardson RFPD, Inc. has launched the ADF4368, a microwave wideband synthesiser from Analog Devices, Inc. The ADF4368 is a high-performance, ultra-low jitter, integer-N and fractional-N phase-locked loop with integrated VCO. It is suitable for frequency conversion applications.

The microwave wideband synthesiser is designed to generate any frequency from 800 MHz to 12.8 GHz without an internal doubler, eliminating the need for sub-harmonic filters. The Σ-Δ modulator includes a 25-bit fixed modulus that allows hertz frequency resolution and an additional 17-bit variable modulus. It requires DC supplies of 3.3 and 5 V.

The ADF4368 is also designed to reduce development time with a simplified serial-peripheral interface register map, external SYNC input and repeatable multichip phase alignment in integer mode and fractional mode. It has a jitter of less than 30 fs and a noise floor of -160 dBc/Hz (at 12.8 GHz). The synthesiser uses the SYNC input or EZSync software programming to support multiple frequency conversions systems, such as MIMO or phased array applications.
