MA26V1100A

Variable capacitance (Varicaps, Varactors) diodes are electronic components used to control television tuners, AM/FM radio receivers, amplifiers, and more. The MA26V1100A variable capacitance diode (VCD) is a variable capacitance diode that can be used in a wide range of applications. This article discusses the application field and working principle of the MA26V1100A VCD.

Applications

The MA26V1100A VCD is ideal for frequency-selective circuits, such as those used in AM/FM radio receivers and television tuners. Its stability and low temperature coefficient make it an ideal choice for application requiring low-phase noise and low distortion. Additionally, it is suitable for RF clamp circuits and adaptive control. The MA26V1100A VCD also has a high common-mode rejection ratio, making it ideal for multipath rejection circuits in FMIF and IFBR Tuners.

The MA26V1100A VCD can be used in other applications as well, including filters, VCOs, oscillators, switches, and power amplifiers.

Working Principle

The MA26V1100A VCD is a two-terminal capacitor whose capacitance is a function of a reverse-voltage applied between the two terminals. The terminals are connected to a diode and an anode, which serves as the Variable Capacitance Terminal. When a bias voltage is applied to the diode, the capacitance of the diode varies. This biasing voltage is controlled by an external voltage source. The higher the voltage, the more the capacitance increases.

The MA26V1100A VCD can provide up to a maximum of 1,100 pF of capacitance. This makes it ideal for applications with high-frequency requirements. The VCD has a low temperature coefficient of -0.09%/°C and is highly stable over large temperature changes.

Conclusion

The MA26V1100A VCD is a variable capacitance diode capable of providing up to 1,100 pF of capacitance. It is suitable for a wide range of applications, including frequency-selective circuits in AM/FM radios, television tuners, IFBR tuners, filter, VCOs, oscillators, switches, power amplifiers and more. Its stability, low temperature coefficient, and high common-mode rejection ratio make it an ideal choice for low-phase noise and low distortion applications.
