DISCRETE SEMICONDUCTORS DATA SHEET alfpage M3D049 BB134 UHF variable capacitance diode Product specification Supersedes data of 1996 May 03 1998 Sep 15 Philips Semiconductors Product specification UHF variable capacitance diode FEATURES Excellent linearity Excellent matching to 0.5% DMA Very small plastic SMD package C28: 1.9 pF; ratio: 10 Low series resistance. MAM130 BB134 handbook, 4 columns k a APPLICATIONS Electronic tuning in UHF television tuners VCO. Fig.1 Simplified outline (SOD323) and symbol. DESCRIPTION The BB134 is a variable capacitance diode, fabricated in planar technology, and encapsulated in the SOD323 very small plastic SMD package. The excellent matching performance is achieved by a direct matching assembly procedure. The unmatched type, BB135 has the same specification.
