Knowles Capacitors AEQ Gain Equalizers

Knowles AEQ Gain Equalizers are designed to modify the gain of specific frequency bands in an audio signal, allowing for precise control over the frequency response of a system. AEQ gain equalizers with monolithic construction, incorporating precision thin-film conductor increases the RF performance. The AEQ gain equalizers operate in the temperature range from -55°C to +125°C with the characteristic impedance of 50Ω. These equalizers are used in automotive audio systems, hearing aid instruments, military radar applications, and satellite systems for their improved audio performance and accurate audio equalization.

Anytime I face a setback, I remind myself progress is two steps forward and one step back. If you’ve ever worked on high-frequency wideband designs, then you know that trying to solve loss slope issues can feel like all your steps are backward. Knowles Precision Devices’ DLI brand of AEQ Gain Equalizers can help you make progress again. AEQ gain equalizers are a circuit compensation solution for loss slope issues created by elements throughout the circuit delivering a gain slope from 1 to 3.5 decibels with a 50-ohm characteristic impedance for EW, ECM, and ECCM broadband microwave modules. Superior RF performance and repeatability is achieved with high dielectric constant ceramics and monolithic construction with a precision thin film conductor. AEQ gain equalizers are available for epoxy attachment and or solder surface mount with a compact size and interchangeable footprint requiring no ground connections, also available in tape and reel packaging for high volume applications and are suitable for use with pick and place equipment.
