Tuner Diodes
FEATURES
♦ Silicon epitaxial planar capacitance
diodes with very wide effective capaci-
tance 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.
♦ This diode is also available in SOD-123 case with
the type designation BB731.
