Synthesisers widen frequency ranges for mmWave designs

The ADF4371 and ADF4372 microwave wideband synthesisers from Analog Devices are in stock at Mouser Electronics. The ADF4371 delivers one of the highest frequency synthesisers in the industry, offering the widest continuous RF output range available — 62MHz to 32GHz — while the ADF4372 operates at 62MHz to 16GHz for designs that do not require the higher frequency.

The microwave wideband synthesisers consist of a phase-locked loop (PLL) with fully integrated voltage-controlled oscillators (VCOs), low-dropout regulators (LDOs), and tracking filter technology.

They feature the industry’s lowest jitter (36fs at 10GHz) and facilitate the implementation of high-resolution fractional-N or integer-N PLL frequency synthesiders when used with an external loop filter and an external reference source.

Compact, at 7mm × 7mm, the synthesisers offer the bandwidth, smaller board space footprint, increased reliability, low noise, and increased clocking range and flexibility to complement a wide range of RF applications such as wireless infrastructure equipment (multicarrier global system for mobile communication (MC-GSM; 5G), test equipment and instrumentation, clock generation, and aerospace and defence-based designs.

For development, the devices are supported by corresponding evaluation boards and an SDP-S Controller Board, also available from Mouser.
