Preliminary specification
UHF variable capacitance diode
BB154
FEATURES
Excellent linearity
Excellent matching to 2% DMA
Very small plastic SMD package
C28: 2.0 pF; ratio: 9.7
Very low series resistance.
APPLICATIONS
Electronic tuning in UHF television tuners
Voltage controlled oscillators (VCO).
DESCRIPTION
The BB154 is a variable capacitance diode, fabricated in
planar technology, and encapsulated in the SOD323 very
small SMD package.
The excellent matching performance is achieved by gliding
matching and a direct matching assembly procedure.
