RLC Electronics’ gain and line loss equalizers combine filter and attenuator technology to achieve a desired response to 40 GHz. The typical curves that follow are representative of commonly requested responses, including both linear and half-sine responses. VSWR is dependent on frequency of operation, complexity of equalized response and bandwidth of response. Power handling is dependent on the physical size of the absorptive elements. Since these elements decrease in size with increasing frequency, power handling by 10 GHz is usually in the hundredths of watts.
