UHF variable capacitance diode
Rev. 01 — 29 January 2009
Product data sheet
1. Product profile
1.1 General description
The BB179BLX is a planar technology variable capacitance diode in a SOD882T
ultra small leadless plastic SMD package. The excellent matching performance is
achieved by gliding matching and a Direct Matching Assembly (DMA) procedure.
1.2 Features
I Excellent linearity
I Excellent matching to 2 % DMA
I Ultra small leadless SMD package
I Cd(28V) :2.1 pF; Cd(1V) to Cd(28V) ratio typical 9
I Low series resistance
1.3 Applications
I Voltage Controlled Oscillators (VCO)
I Electronic tuning in UHF television tuners
