@@k@sh: Noise cancel's for any kind of load as long as they have good matching, there will be noise cancellation, passive load consideration is wrong. To be frank i didn't understand rest of your post, be clear about common mode noise, for example tail current noise will be common mode for all all transistors only when you apply zero differential signal, infact if you apply some large signal to the extent that differential pair current steered to one said then there is no noise cancellation.
@sheldon: How can you say that it is pseudo differential circuit, At the resonance frequency (or LO frequency), of course at dc you are correct but if we can some how manage good ac coupling and proper layout then it has good rejection.
Thanks, Raj.
