Need 2GHz oscillator to feed a binary counter

2ghz+oscillator

Hi,
Any idea about a 2ghz oscillator design to feed an binary counter? The output should have at least 500mv peak to peak to drive the input. Thanks,

vidmar oscillator

look at the 2nd oscillator for the spectrum analyzer made by Matiaz Vidmar at this address : **broken link removed**
It works at 2 GHz abuot and is tunable with a varicap.

stable 2ghz oscillator

Hi pisoiu

If you don't want to have any work with calculating you can use a fully integrated solution from Maxim (www.maxim-ic.com). The MAX2752 is a VCO for the frequency range 1900..2250MHz.

Synergy produces very good 2ghz oscillators which may be used.

Re: 2GHz oscillator

You can design a very good stable oscillator using ceramic resonators, You follow the same design procedures as you would do for a colpits oscillator. For the resonator you should use a ceramic resonator that operators at around 2.7GHz; the resonator is capacitively coupled into the base of the transistor. These oscillators have very good phase noise and are reasonably stable over temperature. Any free running oscillator should be locked to a reference so that it does not drift.

Good Luck

Re: 2GHz oscillator

You can build a lower frequency oscillator and use a multiplier. Only thing that you have to care is to select the right harmonic.

I don't have any idea, but I have some books to follow its

I think in the oscillator output ,you need plus buffer ,if can't offer 500mv ,you need plus an amplifier stage ,then obtain 500mv peak to peak,but so can increase your cost.
