Product specication
VHF variable capacitance diode
BB182
FEATURES
High linearity
Excellent matching to 2% DMA
Ultra small plastic SMD package
C28: 2.7 pF; ratio: 22
Low series resistance.
APPLICATIONS
Electronic tuning in VHF television
tuners, band A up to 160 MHz
Voltage controlled oscillators
(VCO).
DESCRIPTION
The BB182 is a planar technology
variable capacitance diode, in a
SOD523 (SC-79) package. The
excellent matching performance is
achieved by gliding matching and a
direct matching assembly procedure.
