Low cost gain equalisers to compensate for module gain slope
A series of gain equalisers, claimed to be low cost, have been released by Knowles Capacitors.The 0302 size EW series provides slope correction from DC to 18GHz of greater than 3dB. They are designed for repeatable microwave performance to compensate for gain roll-off and VSWR mismatch losses and are a good match to a 50ῼ line width for optimal broadband performance.
The gain equalisers are available in six slopes and are footprint interchangeable for optimising module gain flatness of 1-3.5dB. Solderable terminations are compatible with solder SMT and conductive epoxy assembly and pick and place equipment. No ground connection is required. They are also available in tape and reel packaging for high volume applications, with engineering kits being offered which contain all six slope part types.
Knowles' gain equalisers employ monolithic construction with a precision thin film conductor and resistor films together with proprietary high dielectric constant ceramics for superior RF performance repeatability. Integrated R and C values are realised to produce the desired gain slope. The miniature thin film gain equalisers also have a microwave frequency response which can be modelled by the simple parallel R-C circuit.
