1. Product profile
1.1 General description
The BB182 is a planar technology variable capacitance diode in a SOD523 (SC-79)
ultra small plastic package. The excellent matching performance is achieved by gliding
matching and a Direct Matching Assembly (DMA) procedure.
1.2 Features
I High linearity
I Excellent matching to 2 % DMA
I Ultra small plastic SMD package
I Cd(28V): 2.7 pF; Cd(1V) to Cd(28V) ratio: 22
I Low series resistance
1.3 Applications
I Electronic tuning in VHF television tuners, Band A up to 160 MHz
I Voltage Controlled Oscillators (VCO)
