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.
Features n Excellent linearity n Excellent matching to 1 % DMA n Very small SMD plastic package n Cd(28V): 2.1 pF; Cd(1V) to Cd(28V) ratio: 9 n Low series resistance.
Applications n Electronic tuning in UHF television tuners n Voltage Controlled Oscillators (VCO).
