FEATURES

· High linearity

· Excellent matching to 2% DMA

· Ultra small plastic SMD package

· C28: 2.7 pF; ratio: 22

· Low series resistance.

APPLICATIONS

· Electronic tuning in VHF television tuners, band A up to 160 MHz

· Voltage controlled oscillators (VCO).

DESCRIPTION

The BB182 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.

LIMITING VALUES In accordance with the Absolute Maximum Rating System (IEC 134).
