With a tuning range from 0.5V to 2.5V, the ZV950 series of hyperabrupt varactor diodes meets the requirements of 3V frequency control and filtering systems. The diodes are reported to be characterized ...
The SMV1231-040LF and SMV1233-040LF miniature 0402 varactor diodes are groomed particularly for VCO, phase noise, frequency control, and voltage tuned filter applications including WLAN, CATV low ...
Telecommunication, satellite links and set-top boxes all require tuning a high frequency oscillator. The actual tuning element is a varactor diode, a 2-terminal device that changes capacitance as a ...
You can build nearly any analog circuit from 5 or 3V-only parts; that is, until you try to design a 5V-only, RF VCO using varactor diodes. Because these diodes frequently need drive voltages of 20V or ...
