Richardson RFPD, Inc., an Arrow Electronics company, announced the availability and full design support capabilities for a new microwave wideband synthesizer 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 ideally suited for frequency conversion applications.

The high performance PLL has a figure of merit of −239 dBc/Hz, very low 1/f noise of normalized −287 dBc/Hz and high PFD frequency that can achieve ultra-low in-band noise and integrated jitter. The ADF4368 can 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, which allows even finer resolution and flexibility for frequency planning. It requires DC supplies of 3.3 V and 5 V.

The ADF4368 eases 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 synthesizer uses the SYNC input or EZSync software programming to support multiple frequency conversions systems, such as MIMO or phased array applications.
