BB149
UHF variable capacitance diode
Rev. 6 — 5 September 2011
Product data sheet
1. Product profile
1.1 General description
The BB149 is a variable capacitance diode, fabricated in planar technology, and
encapsulated in the SOD323 (SC-76) very small SMD plastic package.
The excellent matching performance is achieved by gliding matching and a Direct
Matching Assembly (DMA) procedure. The unmatched type, BB159 has the same
specification.
1.2 Features and benefits
Excellent linearity
Excellent matching to 1 % DMA
Very small SMD plastic package
Cd(28V): 2.1 pF; Cd(1V) to Cd(28V) ratio: 9
Low series resistance.
1.3 Applications
Electronic tuning in UHF television tuners
Voltage Controlled Oscillators (VCO).
