7 GHz to 28 GHz Low phase Noise Fractional-N Synthesizer
It uses a reference input ranging from 25 MHz to 300 MHz, either generated with a Crystal and the integrated Crystal Oscillator or provided from an LVDS driver.
The WEA728S45G generates RF signals spanning from a frequency of 7 GHz up to 28 GHz using a bank of four integrated VCOs a RF frequency doubler.
The synthesizer integrates automatic VCO and VCO-Band selection system.
The WEA728S45G is powered by 1.8 V supply.
It is implemented in the GlobalFoundries 45RFSOI process.
