Maybe, but that's starting to increase the complexity.  I've used 
various and sundry harmonic mixers using SRDs (aka Sampling Phase 
Detectors)  The SRD has very fast transition times, so getting well up 
into microwave is easy.

For my application, I'm happy down at 15 MHz, and a reasonably fast rise 
time on a 1 microsecond pulse does it quite nicely.
