MAM130 BB147 handbook, 4 columns k a APPLICATIONS Electronic tuning in television tuners with extended VHF range Voltage controlled oscillators (VCO). DESCRIPTION The BB147 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.
