Product specication
VHF variable capacitance diode
BB187
FEATURES
High linearity
Excellent matching to 2% DMA
Ultra small plastic SMD package
C25: 2.75 pF; ratio: min. 11
Low series resistance.
APPLICATIONS
Electronic tuning in VHF television tuners
Voltage controlled oscillators (VCO).
DESCRIPTION
The BB187 is a variable capacitance diode, fabricated in
planar technology and encapsulated in the SOD523
(SC-79) ultra small plastic SMD package. The excellent
matching performance is achieved by gliding matching
and a Direct Matching Assembly (DMA) procedure.
