power dividers & couplers

 

From broadband directional couplers, to low loss crossover couplers and TEMlineTM hybrid Couplers, you will find that all models feature high power handling, multiple octave bandwidths and low loss and meet MIL-E-5400 Class 3 or equivalent screening. API Technologies’ Directional Couplers feature multi-octave broadband performance, high power handling of up to 1500 watts and low flatness as low as +/- 0.4 dB.

API Technologies Power Dividers are designed with high isolation and exceptional phase balance in mind. Our Wilkinson style power dividers yield superior isolation between the output ports. Our printed circuit board power dividers are a low cost solution. Stripline and microstrip styles can be produced without the high cost of lumped inductors or capacitive elements.

Wirline® and Wirepac®

Wireline and Wirepac quadrature couplers and hybrids, developed and patented by Sage Laboratories, consist of a pair of wire center conductors surrounded by a continuous dielectric insulator and shielded by a drawn or extruded metallic jacket. The resultant construction has the physical attributes of semi-rigid coaxial cable and the electric performance of a precision TEM mode parallel coupled line coupler.

Electrical Performance includes frequency independent quadrature output phases, low VSWR, low insertion loss, high directivity and freedom from intermodulation products.

Features

Octave Band Performance

  • Wireline products feature the performance characteristics of an octave band 3 dB quadrature hybrid.
  • Wireline products feature a formable construction similar to semi-rigid cable.
Low Loss

  • The Wireline coupler insertion loss is defined as input power minus the sum of all output powers.
  • Insertion loss is typically less than 0.3 or 0.4 dB over the frequency range.
  • Wirepac insertion loss is typically less than 0.2 dB over the operating frequency range.
Value Added Features

  • API has long standing aerospace and commercial heritage with the Wireline and Wirepac product lines.
  • Our Wireline, tin plate and bare finish products are RoHS Compliant. Product is EAR99.
Applications

  • 3 dB Quadrature hybrid coupler
  • Directional coupler
