Active Band Pass Filter  Opamp Band Pass Filter

Active Band Pass Filter Opamp Band Pass Filter

In a Band Pass Filter circuit, the overall width of the actual pass band between the upper and lower 3dB corner points of the filter determines the Quality Factor or Qpoint of the circuit. This Q Factor is a measure of how Selective or Unselective the band pass filter is towards a given spread of frequencies. The lower the value

Abstract A tunable thirdorder combline bandpass filter using thinfilm bariumstrontiumtitanate varactors and fabricated on a sapphire substrate is reported. Application of 0200V bias varied the center frequency of the filter from 2.44 to 2.88 GHz (16% tuning) while achieving a 1dB bandwidth of 400 MHz.

the standard bandpass filter design scheme is generally applied. Since the Q values of the varactor diodes are low, they are the major source of the insertion loss of the tunable bandpass filters. Therefore, varactortuned active bandpass filters have been introduced. These techniques lead the microwave active filters to
