Introduction

Electronic warfare applications, test & measurement, MILCOM, Radar and more.  APITech gain equalizers deliver simple solutions for your system slope problems. Designed, tested, manufactured and supported by our Inmet brand, APITech gain equalizers have become the industry standard. We offer negative, positive, parabolic equalizers and fine grain equalizers, and in tubular and rectangular styles depending on slope and frequency requirements.

Overview

Choose the gain equalizers you need by frequency range, dB values (slope), connector type, body style, and any other requirements, including environmental. Both standard and custom-designed equalizers are available. Equalizers can be custom made to meet the desired performance parameters and package configurations for each application.

Features include:

  • DC to 40 GHz, high performance
  • Broadband or narrowband frequency performance
  • Fine grain tuning capability
  • Standard connectors: SMA, 2.9mm, N, TNC, SMP and 2.4mm
  • Meets MIL-SPEC environmental requirements
  • Tubular (fixed negative slope; fixed positive slope)
  • Rectangular (fixed or field adjustable)
  • Standard models and “engineered to order” equalizers available depending on slope and frequency requirements
  • Detailed datasheets available for all standard models, and performance illustrations available by type

Competitive Advantage

APITech has engineering staff devoted exclusively to its gain equalizer product line. Rare in this industry.  With over 2,500 active gain equalizer designs, and more than 200 customer applications worldwide. We can supply both standard and custom-designed equalizers to meet the needs of both commercial and defense.

Explore our line of gain equalizers for all your needs:

  Negative Slope: typically used for applications to offset the excessive loss of long cable runs at high frequencies. The loss characteristic of the equalizer decreases linearly with frequency. negative_slope_equ

 

positive_slope_equ

 

Positive Slope: typically used for applications to offset excessive loss of low frequencies where waveguide transmission characteristics require an equalizer that has increasing attenuation with frequency.  
  Parabolic: used in applications where a broadband traveling wave tube (TWT) or solid state amplifiers (SSA) has maximum gain at or near the center of the frequency band. parabolic_equ

 

fine grain equ

 

Fine Grain: used to flatten gain ripple and spikes in a broadband application. The narrow band attenuation is adjustable in the bands where the ripple or spikes occur and flatten the response in these sub bands.
