PFD capable of identifying 2.4G analog signals

Our system need a PLL to output  very stable 2.4G analog sinusoidal  signals,we know many chips can do that. But in our system,the situation may be different from the usuals. In our system ,we will give PFD 2.4G analog signals,than we hope it come through charge pump, loop filter and vco, the signals which create by vco would be disturbed by noise and than send back to PFD。It means we need a chip works as a  traditional PLL to deal with two 2.4G analog signals,one is stable ,the other whose frequency is stable(2.4G) but the phase varies. At last, the vco out a 2.4G analog signals which could compensate phase jitter.

We want to know if chips like HMC7044 could do that.
