NORWOOD, Mass. – Analog Devices Inc. (ADI) in Norwood, Mass., is introducing the ADF4371 state-of-the-art synthesizer for RF and microwave systems in aerospace and defense applications, as well as test and measurement, communications infrastructure, and high-speed converter clocking.
The ADF4371 consists of a phase-locked loop (PLL) with integrated voltage controlled oscillator (VCO) as well as integrated low dropout regulators (LDOs) and integrated tracking filter.
Designed using ADI’s 25 years of leading RF and microwave synthesizer expertise, the ADF4371 offers continuous RF output range of 62 MHz to 32 GHz, low PLL FOM (-234dBc/Hz), low spurious (-100dBc typ.), low VCO phase noise (-134dBc/Hz @1 MHz offset at 8 GHz), and built-in tracking filter technology.
Its configurable architecture means that designers can choose one, compact, synthesizer solution to cover almost any LO/clock requirement within these frequency ranges, thereby reducing development costs, risk and time to market.
The ADF4371 facilitates high-resolution (39-bit) fractional-N or integer-N PLL frequency synthesizers when used with an external loop filter and an external reference source. The wideband microwave VCO design helps generate frequencies from 62.5 MHz to 32 GHz.
The ADF4371 supports integrated power supply decoupling, integrated LDOs, and integrated harmonic tracking filters. The tracking filter facilitates at least 30dB harmonic and sub-harmonic rejection across the VCO range.
