Spectrum Control's Inmet Brand Gain Equalizers offer simple solutions to your system slope problems. Negative, Positive or Parabolic slope units can be built to meet your desired performance parameters in the DC-40 GHz frequency range.
40GHz Equalizers, broadband, custom-designed equalizers, SMA Gain equalizers are passive microwave components that have an insertion loss characteristic that varies as a function of frequency. Spectrum Control can supply both standard and custom-designed equalizers to meet the needs of commercial and military customers alike. Spectrum Control has the engineering staff devoted exclusively to this product line and can supply designs that precisely define a preset loss characteristic (fixed equalizers) or with the ability to be loss-adjusted to custom-fit the particular variable requirements needed to field-tune a system. Each equalizer application has an insertion loss characteristic and package configuration that is unique. Equalizers can be custom-made to meet the desired performance parameters and package configurations for each application.
Negative Slope equalizers are 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.
Positive Slope equalizers are typically used for applications to offset excessive loss of low frequencies where waveguide transmission characteristics require an equalizer that has increasing attenuation withh frequency.
Parabolic equalizers are used in applications where a broadband traveling wave tube (TWT) or solid state amplifies (SSA) has maximum gain or near the center of the frequency band. The characteristics of the equalizer require maximum attenuation at mid-band and decreasing attenuation at band edges. Conversely, an inverted parabolic equalizer has decreased attenuation at mid-band and increasing attenuation at band edges.
Fine Grain equalizers are 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.
