BB149
UHF variable capacitance diode
Rev. 05 -- 4 October 2004 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
s s s s s 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
s Electronic tuning in UHF television tuners s Voltage Controlled Oscillators (VCO).
