Blocker Noise Figure / Reciprocal Mixing Noise test using SpectreRF (MMSIM14)

RFStuff over 10 years ago

Dear All,

I want to see/simulate how a close in blocker affects my receiver noise in the presence of LO-phase noise.

I provide a square LO to my receiver Mixer and a Blocker at the receiver input.

May be I have to model the LO phase noise in Verilog-A & then do a Pnoise analysis. ( But beat frequency reduces quite considerably with respect to LO frequency because of close in Blocker )

Can anybody please comment and give suggestion how to do this type of simulation efficiently in SpectreRF ?

Kind Regards,

Parents

This is probably the article that Andrew had in mind.
