Product Description: BB914 Infineon Technologies

The BB914 is a varactor diode from Infineon Technologies. Varactor diodes are variable capacitance diodes, meaning that their capacitance changes with the applied voltage. This makes them useful for a variety of applications, such as frequency tuning, voltage control, and signal modulation.

The BB914 is a dual diode common cathode device, meaning that it contains two diodes with a common cathode terminal. This makes it ideal for use in applications where two diodes need to be matched, such as in FM radio tuners.

The BB914 is designed for use in FM radio tuners with extended frequency bands. It has a high tuning ratio at low supply voltage, making it ideal for use in car radios. It is also a monolithic chip, which means that the two diodes are integrated into a single package. This ensures perfect dual diode tracking.

The BB914 has a good linearity for C-V curve, which means that its capacitance changes linearly with the applied voltage. This makes it suitable for a variety of applications where precise frequency tuning is required. The BB914 also has a high figure of merit, which means that it is very efficient at converting electrical energy into RF energy.

The BB914 is Pb-free (RoHS compliant) and comes in a SOT23 package. It is suitable for use in a wide variety of applications, including:

• FM radio tuners
• Voltage-controlled oscillators (VCOs)
• Phase-locked loops (PLLs)
• Frequency multipliers
• Signal mixers
• Detectors
