DISCRETE SEMICONDUCTORS DATA SHEET alfpage M3D049 BB149A UHF variable capacitance diode Product specification 1997 Dec 17 Philips Semiconductors Product specification UHF variable capacitance diode FEATURES Excellent linearity Excellent matching to 2% DMA Very small plastic SMD package C28: 2.1 pF; ratio 9 Low series resistance. APPLICATIONS Electronic tuning in UHF television tuners Voltage controlled oscillators (VCO). PINNING PIN 1 2 DESCRIPTION cathode anode DESCRIPTION The BB149A is a planar technology variable capacitance diode, in a SOD323 very small plastic SMD package. The excellent matching performance is achieved by gliding matching and a direct matching assembly procedure. BB149A handbook, 2 columns 1 2 MAM392 Marking code: PL. Cathode side indicated by a bar.
