7 GHz PLL frequency synthesizer for RF local-oscillator chains
The Analog Devices ADF4107BRUZ-REEL7 is a single-circuit PLL frequency synthesizer designed for clock generation in RF systems. The part covers a maximum frequency of 7 GHz, making it suitable for local-oscillator synthesis in satellite downconverters, microwave point-to-point radios, and test equipment that needs a clean, programmable LO up to C-band. The 16-TSSOP package keeps the footprint small on dense RF boards.
The 2.7 V to 3.3 V supply range matches common 3.3 V RF logic and VCO supply rails; no extra regulator is needed if the board already runs 3.3 V. The single 2:1 input-to-output ratio means one reference input and one feedback input — standard for a single-loop PLL.
