Product specification
VHF variable capacitance diode
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

(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.
