1. Product profile
1.1 General description
The BB189 is a planar technology variable capacitance diode in a SOD523 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 1.8 % DMA
I Ultra small plastic SMD package
I C_d(25V) : 2.05 pF; C_d(2V) to C_d(25V) ratio: 6.3 min.
I Low series resistance
1.3 Applications
I Voltage Controlled Oscillators (VCO)
I Electronic tuning in UHF television tuners
