RE: Freq to voltage converter
I have checked most of the semiconductor manufactureres, Only Analog Devices & TI carry them but works up to 1MHz.
Very flexible as far as requirements, any power supply voltage, any output voltage vs. input freq (~10MHz).
I hope, this answers your Q's. Tahnks again
RE: Freq to voltage converter
Why not divide by ten and feed into the parts you found?

2) A phase locked loop (PLL) makes a good F to V. The input signal to the VCO is proportional to the input frequency.
You may be able to find integrated solutions to the above techniques in RF IC's.
RE: Freq to voltage converter
A LP filter on the output of the one-shot gives you a voltage quite proportional to the input frequency.
As IRstuff mentions, it might be an idea to create the one-shot in logic (for instance with a 74HC74, 1/4 74HC08 and a fast enough clock). This will give a much more stable result. (time, temperature etc.)

Of course it is you who are to be credited for the logic one-shot
