DISCRETE SEMICONDUCTORS DATA SHEET alfpage M3D049 BB154 UHF variable capacitance diode Preliminary specification 1999 May 12 Philips Semiconductors Preliminary specification UHF variable capacitance diode FEATURES Excellent linearity Excellent matching to 2% DMA Very small plastic SMD package C28: 2.0 pF; ratio: 9.7 Very low series resistance. 4 columns BB154 PINNING PIN 1 2 cathode anode DESCRIPTION k 1 a 2 APPLICATIONS Electronic tuning in UHF television tuners Voltage controlled oscillators (VCO). DESCRIPTION The BB154 is a variable capacitance diode, fabricated in planar technology, and encapsulated in the SOD323 very small SMD package. The excellent matching performance is achieved by gliding matching and a direct matching assembly procedure. LIMITING VALUES In accordance with the Absolute Maximum Rating System (IEC 134).
