Basic Considerations for Specifying RF & Microwave Filters

From Anatech Electronics, Inc.
 

 

As one of the fundamental signal processing components in RF and microwave circuits, the filter plays a critical role in determining any
system's ultimate performance. Since the electromagnetic spectrum has become more and more densely populated, filter performance has
taken on greater significance than ever because interference rejection is of paramount importance.

Products & Services
RF band pass filters are active or passive circuits that pass signals from a specific frequency band and reject signals from out-of-band frequencies. Surface acoustic wave (SAW) filters, crystal filters, and cavity filters are types of band pass filters.

RF power dividers and RF power combiners are circuits that accept input signals and deliver multiple outputs that are equal in phase and amplitude. There are two basic product categories: passive and active. Search by Specification | Learn more about RF Power Dividers and RF Power Combiners
RF diplexers are three-port frequency-dependent devices that may be used as a separator or a combiner of signals. RF duplexers allow a transmitter operating on one frequency and a receiver operating on a different frequency to share a common antenna with a minimum of interaction and degradation of the different RF signals.

RF filters and microwave filters are devices that pass or reject signals by frequency. Basic types include bandpass filters, band reject filters, low pass filters, and high pass filters. Search by Specification | Learn more about RF Filters and Microwave Filters
RF 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. Search by Specification | Learn more about RF Band Reject Filters
