RF Filters are essential components of electronic communication systems, with the purpose of separating signals with different bandwidths, passing, attenuating or blocking frequencies. The AEQ05510-10 is a new RF filter with advanced features that make it a reliable, high-performance product. This article examines the application field and working principle of the AEQ05510-10.

Design and Specifications

The AEQ05510-10 is a 5-10 MHz band-pass filter in a small form factor. It is designed for transmitting or receiving narrowband signals. It is constructed with dielectric materials such as alumina, and features a dielectric resonance structure, an adjustable envelope, and a Coplanar Waveguide (CPW) track for improved performance. The AEQ05510-10 has a frequency response of 10 dB at –3 dBV. The center frequency of the filter is 5-10 MHz, and its stopband rejection is 160 dB. It also features an insertion loss of less than 0.25 dB, a maximum passing signal of 5 dBV, and a maximum return loss of 20 dB.

Applications

The AEQ05510-10 filter can be used in a variety of communication systems. It is suitable for use in public safety and military band radios, where narrowband channels allow for better signal quality than broader bands. It can be used in short-range point-to-point links and in local area networks to filter out noise and reduce interference. It can also be used in mobile and satellite communication systems for frequency division multiple access (FDMA) and Time Division Multiple Access (TDMA) applications. Additionally, the AEQ05510-10 provides interference rejection and immunity in digital cellular and Wideband Code Division Multiple Access (WCDMA) systems.

Working Principle

The working principle of the AEQ05510-10 filter is based on an asymmetrical stepped slot located across its center. This asymmetrical stepped slot prevents higher order modes of the filter from propagating. The CPW track of the AEQ05510-10 also helps to reduce the insertion loss and to enhance the stopband rejection. The dielectric resonance structure of the filter causes it to reject frequencies that are too close to the center frequency and increase the selectivity of the filter.

The AEQ05510-10 can be used for efficiently rejecting signals outside its passband and for improving the signal-to-noise ratio within its passband. The filter can also be used to reduce the intermodulation distortion of signals. The AEQ05510-10 is a high-performance RF filter with excellent filter characteristics including high stopband suppression, low insertion loss, and high return loss.

Conclusion

The AEQ05510-10 is a compact 5-10 MHz band-pass filter, designed for transmitting or receiving narrowband signals. It can be used in a variety of communication systems, such as public safety and military band radios, short-range point-to-point links, local area networks, and digital cellular systems. Its working principle is based on an asymmetrical stepped slot located across its center, which together with its CPW track, dielectric resonance structure, and adjustable envelope, provide superior filter characteristics. It is an ideal choice for applications that require high selectivity, low insertion loss, and high stopband suppression.
