BB199 Variable capacitance diode for VCO and VCXO Rev. 1 1 December 2010 Product data sheet 1. Product profile 1.1 General description The BB199 is a low voltage variable capacitance diode for the Voltage Controlled Oscillator (VCO) and Voltage Controlled Crystal Oscillator (VCXO) applications. CAUTION This device is sensitive to ElectroStatic Discharge (ESD). Therefore care should be taken during transport and handling. 1.2 Features and benefits Small plastic SMD package Very low operating voltage (1 V to 4 V) Large capacitance ratio (C /C = 2.8 minimum) d(0V5) d(2V) Good capacitor-voltage (C-V) linearity Very low series resistance allowing high Q performance. 1.3 Applications Communication equipment Voltage Controlled Oscillators 2.
