Product specification
VHF variable capacitance diode
FEATURES
• High linearity
• Excellent matching to 2% DMA
• Ultra small plastic SMD package
• C25: 2.8 pF; ratio: 17
DESCRIPTION
The BB182B is a planar technology
variable capacitance diode in a
SOD523 (SC-79) package. The
excellent matching performance is
achieved by gliding matching and a
