... Figure 1 ISSUE 3 - APRIL 2001 Most textbook circuits show a single variable capacitance diode in place of the ZDC834A. In practice radio frequency oscillations in the tank circuit can drive the single diode into conduction on peaks increasing the bias voltage and giving rise to undesirable harmonics. Common-cathode variable capacitance diodes are used to overcome this problem ...

... As this is a final test measurement customers will not have the option to specify a capacitance at the time of ordering and will be obliged to accept the band into which the devices are tested. Should this be of interest the specification identification would change from ZDC834A to FSD271 and - Purchase orders can be placed in multiples of 3000 units / reel for device type FSD271TA - Samples can be obtained from Zetex Plc quoting device type #FSD271TA Zetex plc ...
