Active filters are electronic filers that use active components such as voltage amplifiers or operational amplifiers. The amplifier shapes and stabilizes the behavior of the filter, and serves as a buffer interface to the driven component. Search by Specification | Learn More about Active Filters

Active noise and vibration control systems are products such as controllers, sensors and actuators that monitor and cancel noise and/or vibration. Learn More about Active Noise Control Products

RF isolators and RF circulators are passive devices used to control the propagation of an RF signal. Search by Specification | Learn More about RF Isolators and RF Circulators

RF waveguide isolators and RF waveguide circulators permit a signal to pass in one direction while providing high isolation to reflected energy in the reverse direction. RF waveguide circulators are passive devices with three or more ports. Learn More about RF Waveguide Isolators and Circulators

Active low pass filters pass signals from low frequencies and reject signals from high frequencies. Search by Specification | Learn More about Active Low Pass Filters

Fiber optic circulators are nonreciprocal devices that direct a light signal from one port, via a fiber optic line, to another sequentially. Learn More about Fiber Optic Circulators

Active band pass filters are used to attenuate frequencies below and above a range of frequencies (i.e., the bandwidth or passband of the filter). Learn More about Active Band Pass Filters

Active band reject filters are tuned circuits that prevent the passage of signals within a specified band of frequencies. These devices are also known as bandstop or notch filters. Learn More about Active Band Reject Filters

Active high pass filters pass signals from high frequencies and reject signals from low frequencies. Learn More about Active High Pass Filters
