Dual varactors ensure close matching
For applications needing close tuner diode matching, Zetex has released a pair of dual common-cathode hyperabrupt varactors.
For applications needing close tuner diode matching, Zetex has released a pair of dual common-cathode hyperabrupt varactors The ZMDC831BTA and ZMDC832BTA offer high tolerance CV characteristics, low leakage and an accordingly low phase noise performance
Nominal capacitances for the 831B and 832B are just 15 and 22pF, respectively, for a reverse bias voltage of 2V and a frequency of 1MHz.
Reverse voltage leakage current is typically as low as 0.2nA.
By housing two matched devices in a single miniature package, board space savings can also be made.
A maximum footprint of 2.2 x 2.2mm is required by the component's SOT323 outline.
Typical applications for the ZMDC dual varactors include voltage controlled oscillators and tuned phase lock loop tank circuits.
