Discrete Filters

Bandpass, Low Pass, High Pass, or Notch

Miniature discrete component filters are designed to give optimal performance where small size is critical. Electrical and mechanical requirements for each design are computergenerated, taking into consideration realizable “Q” and environmental conditions, then analyzed using our unique software, thereby reducing the amount of trial and error alignment.

Overview

Filter designs are available to satisfy bandpass, lowpass, highpass, or bandreject applications. We have found through our years of service that one design does not fit all needs. In order to achieve today’s required electrical performance, Smiths Interconnect’s engineers use a variety of electrical circuits ranging from coupled tank, mesh, resonant ladder, highpass/lowpass, or helical to achieve the desired performance. In some cases, a combination of circuit designs is used. This enables our engineers to provide you with the highest performance filters available.

Smiths Interconnect has developed a series of package types to satisfy the majority of industry needs. These range from small TO8 packages to 1/4-wave designs. Actual package selection will depend upon your specific performance needs. All machining is done on computer-controlled machines, thereby reducing error and assuring repeatability of critical processes. Our designs incorporate high “Q” air wound or toroidal inductors and monolithic ceramic capacitors. Regardless of the application, our internal processes and procedures help ensure that all filters are fully compliant to customers’ specifications
