When voltage is applied to a Voltage-Controlled Oscillator (VCO), the oscillator generates a tunable output frequency based on the control voltage. The varactor diode adjusts its capacitance, altering the resonant frequency of the LC tank circuit, which in turn changes the output frequency. VCOs are... read more

Crystal filters with more than two poles offer enhanced performance, including steeper roll-off, narrower passbands, and improved stopband attenuation. Each additional pole increases the filter’s selectivity and out-of-band rejection, making them ideal for applications requiring precise frequency se... read more

When a frequency is applied to a crystal filter, the piezoelectric properties of the quartz crystal cause it to vibrate at its resonant frequency. The filter selectively allows frequencies within its passband to pass with minimal loss while attenuating out-of-band frequencies. This high selectivity ... read more

A Phase-Locked Loop (PLL) is a feedback control system that synchronizes the phase and frequency of an output signal with a reference signal. It consists of a Phase Detector (PD), Low-Pass Filter (LPF), and Voltage-Controlled Oscillator (VCO), working together to achieve phase locking. PLLs are esse... read more
