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.
