13 GHz PLL synthesizer for microwave signal chains
The ADF4159CCPZ-RL7 is a PLL frequency synthesizer that accepts CMOS or TTL reference inputs and delivers a CMOS output, with a maximum operating frequency of 13 GHz. That puts it squarely in the microwave band — think point-to-point radio, satellite downconverters, or test equipment local oscillators where the phase noise floor and lock time matter more than raw logic speed. The 2:1 input-to-output ratio allows feeding from a divided-down reference or a direct oscillator.
