Tuner Diodes
Features
• Silicon epitaxial planar capacitance diodes with
very wide effective capacitance variation for tuning
the VHF range 41 ... 170 MHz in hyperband
television tuners.
• These diodes are available as singles or as matched
sets of two or more units according to the tracking
condition described in the table of characteristics.
