Help me identify a VCP package with SMC VFC430-480 markings

I′m fixing a RF transmitters in 430-480Mhz band, and probaly I find a VCO with problem. In the VCO package say: SMC VFC430-480. I soppose that is a old microwave RF company. In order to get a new VCO part, I need know the specs of this one.

Does Anyone know that company?

I searched in the google and don't know what it is. But I found that maybe a harmonic oscillator. And maybe VFC is voltage freq converter (harmonic oscillator). Hope it will helpyou.

If you cannot find the spec of the oscillator, you can try to evaluate yourself the existing one.
Supply it using a battery, check for frequency range, tuning gain, output power, stability, phase noise, pulling, pushing, etc.

If the oscillator can't work and can't be tested, you can evaluate it's performance according to the transmitter specification.

May be, it is something like this VFC490SA datasheet and Application Note, Data Sheet, Circuit, PDF, Pinout | Datasheet Archive and SMC=Synergy Microwave Corporation.
Try to ask them.
