Rapid Filter Centers

  • Available from APC, API offers rapid cell lumped element filters covering 1 MHz-3 GHz in lowpass designs with the following options: SMA connectors, surface mount or PC pin.
  • Rapid filter solutions are ideal for moderate complexity, standard design options.
  • Applications include harmonic rejection.

Wide Range of Topologies

  • API’s lowpass filter expertise includes lumped element, tubular and suspended substrate designs.

Creative Layouts

  • Utilising sophisticated software such as sonnet EM simulator and SolidWorks, creative layouts can be realised to optimise package size and electrical performance.

Tubular Filters

  • Tubular filters offer extremely high ultimate rejection, low insertion loss and high power handling.

Innovative Designs

  • In order to optimise performance in a given package size, API Technologies engineers can utilise multiple topologies in a single design.
  • Its key manufacturing facilities also incorporate strategic disciplined processes including APQP (Advanced Product Quality Planning) to ensure that a specific, structured sequence of operations are completed to prevent potential quality problems.
