UHF variable capacitance diode
FEATURES
· Excellent linearity
· Excellent matching to 2% DMA
· Ultra small plastic SMD package
· C28: 2.1 pF; ratio: 9
· Low series resistance.
APPLICATIONS
· Electronic tuning in UHF television tuners
· Voltage controlled oscillators
DESCRIPTION
The BB179B is a planar technology variable capacitance diode, in a SOD523 (SC-79)
package. The excellent matching performance is achieved by gliding matching and a
direct matching assembly procedure.
