DISCRETE SEMICONDUCTORS DATA SHEET alfpage M3D049 BB148 VHF variable capacitance diode Product specification Supersedes data of 1996 May 03 1998 Sep 15 Philips Semiconductors Product specification VHF variable capacitance diode FEATURES Excellent linearity Excellent matching to 1% DMA Very small plastic SMD package C28: 2.6 pF; ratio: 15 Low series resistance. MAM130 BB148 handbook, 4 columns k a APPLICATIONS Electronic tuning in VHF television tuners, band B up to 460 MHz VCO. DESCRIPTION The BB148 is variable capacitance diode, fabricated in planar technology, and encapsulated in the SOD323 very small plastic SMD package. The excellent matching performance is achieved by gliding matching and a direct matching assembly procedure. The diodes are delivered on tape in several matched groups and are also available unmatched upon request. The unmatched type, BB158 has the same specification.
