Philips Semiconductors Product specification
UHF variable capacitance diode BB134
FEATURES
•Excellent linearity
•Excellent matching to 0.5% DMA
•Very small plastic SMD package
•C28: 1.9 pF; ratio: 10
•Low series resistance.
APPLICATIONS
•Electronic tuning in UHF television tuners

DESCRIPTION
The BB134 is a variable capacitance diode, fabricated in
planar technology, and encapsulated in the SOD323
(SC-76) very small plastic SMD package.
The excellent matching performance is achieved by a
direct matching assembly procedure. The unmatched
type, BB135 has the same specification.
