The MA26V0700A Variable Capacitance Diode (Varicap/Varactor) is a Schottky barrier diode that acts as a voltage-controlled capacitor. It is ideal for many applications such as frequency synthesizer circuits, voltage-controlled oscillators (VCOs), phase-locked loops (PLLs), and FM detectors.

MA26V0700A Application Field

The MA26V0700A is a good choice for a variety of circuits that require fast frequency-setting and tuning capabilities. A common application for the MA26V0700A is in frequency synthesizers. When used in this type of circuit, it is typically connected to a voltage-controlled oscillator (VCO). When the voltage is applied across the diode, it increases the capacitance, which changes the frequency of the VCO.

Another common application of the MA26V0700A is in phase-locked loops (PLLs). This type of circuit is used for digital signal processing and communication, and it uses electronic control systems to maintain precise timing. In a PLL, the MA26V0700A is connected to a frequency-to-voltage converter where it adjusts the phase difference to keep the signal in phase with the input reference signal.

The MA26V0700A can also be used in FM detectors. This type of circuit is used to amplify and detect signals in the FM radio frequency range, and the MA26V0700A is connected to a reactance modulator to control the gain of the amplifier circuit.

MA26V0700A Working Principle

The MA26V0700A operates by using a biased Schottky junction. When bias is applied, the diode can control the reverse bias voltage applied across it. This results in a decrease in depletion layer width, which increases the junction capacitance. Therefore, the capacitance of the diode is proportional to the reverse bias voltage applied.

The MA26V0700A has a low capacitance ratio, which is the ratio between the capacitance at the maximum and the minimum reverse bias voltage. This ratio can range from 1.5 to 2.5, which allows the diode to have a wide range of capacitance, depending on the reverse bias voltage applied.

The MA26V0700A is also highly stable and offers low noise performance. It is also capable of operating over a wide range of temperatures and can handle high current densities. This makes it an ideal choice for many frequency-tuning and communication applications.
