The WEA56HPS45 is a 3-Octave Fractional-N frequency synthesizer. It accepts a 100 MHz to 800 MHz Input Reference Clock and generates a 7 GHz to 56 GHz output. It provides a >0dBm output from a single pin for all frequencies. It integrates a bank of four VCOs with 128 subbands. It is implemented in the GlobalFoundries 45RFSOI process metal option 18. The PLL integrates a reference Doubler, a programmable Charge Pump, a low noise Phase Detector with lock detect indication, a mmWave Prescaler and a programmable MASH. The synthesizer is powered by a 1.0 V and 1.8 V supplies
