I have RF VCO module. I have 2 inputs Vcc (Power supply at 5V). Then I have modulating signal 0-4.5V. What should I do with the modulating signal? Can I short it to the GND (The GND on the VCC)? What is the modulating signal for? It is 1.2GHz VCO module. I need the VCO to be in the Box. It is not for a bench testing. If anybody have a reference for VCO book or manual that would be great.
Thanks
