RF filters can be either passive or active, depending on their design and functionality. Passive RF filters use components like inductors, capacitors, and resistors to filter signals without external power, making them ideal for simple frequency selection. Active RF filters incorporate amplifiers, t... read more

A crystal filter is classified as a passive device because it operates without external power, relying solely on the piezoelectric properties of quartz crystals and passive components (capacitors, inductors). Unlike active filters, it cannot amplify signals—only filter specific frequencies through m... read more

While both oscillator crystals and crystal filters rely on quartz's piezoelectric properties, they serve different functions in electronics. Oscillator crystals generate precise frequencies for clocks, RF sources, and microcontrollers, prioritizing stability and low ESR. In contrast, crystal filters... read more
