UHF variable capacitance diode
Rev. 02 — 5 October 2004
Product data sheet
1. Product profile
1.1 General description
The BB179 is a planar technology variable capacitance diode, in a SOD523 (SC-79) ultra
small plastic SMD package. The excellent matching performance is achieved by gliding
matching and a Direct Matching Assembly (DMA) procedure.
1.2 Features
■ Excellent linearity
■ Excellent matching to 2 % DMA
■ Ultra small plastic SMD 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).
