DISCRETE SEMICONDUCTORS DATA SHEET alfpage M3D049 BB146 UHF variable capacitance diode Product specification 1996 Sep 20 Philips Semiconductors Product specification UHF variable capacitance diode FEATURES Ultra high ratio Excellent matching to 1.6% DMA (Direct Matching Assembly) Very small plastic SMD package C28: 1.9 pF; ratio 20. MAM130 BB146 handbook, 4 columns k a APPLICATIONS Electronic tuning in television tuners with extended UHF range Voltage controlled oscillators (VCO). DESCRIPTION The BB146 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 gliding matching and a direct matching assembly procedure. ELECTRICAL CHARACTERISTICS Tj = 25 °C; unless otherwise specified.
