For designs where tuner-diode matching is critical and space is limited, the ZMDC831BTA and 832BTA dual common-cathode, hyperabrupt varactor diodes report high tolerance C-V characteristics, inherent ...

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 ...

How does a varactor diode work? To form the PN junction that makes a diode, half the piece is doped with a trace amount of “donor atoms” that have one more electron than the intrinsic stuff to make ...
