The FSD270 is a new hyperabrupt SOT23 packaged dual common cathode varactor diode , offering users both compact circuit design and impressive performance comprising tightly controlled CV characteristics, a capacitance of typically 33 pf @ 2V,excellent phase noise performance and high Q of 200 min. This superior performance in the VHF and UHF ranges has been optimised to meet the high filtering requirements of a wide range of Digital Audio Broadcasting (DAB) module circuits , mobile radios, pagers, voltage controlled crystal oscillators (VCXO) and temperature controlled crystal oscillators (TCXO).
