ECHO Microwave is developing another filter lines such as Thin-Film and substrate Filters, especially for high frequency bands up to 40GHz. We already have good filter solutions as cavity, ceramic, LC and SIW, but we expect the thin-film and substrate filters to be good choices for your high frequency application such as Military, Radar, Aerospace and Satellite Communication System.

Alumina thin film filters represent a cutting-edge advancement in the realm of RF (radio frequency) devices. These innovative filters, constructed on microstrip alumina substrates, offer a remarkable combination of features, making them an ideal choice for various applications.

The thin film technology employed in these filters ensures their compactness, light weight, and small footprint, making them well-suited for contemporary electronic devices where space efficiency is paramount. This feature is particularly advantageous for small surface-mount applications, allowing for seamless integration into compact electronic systems.

One of the key advantages of these filters lies in their ceramic substrate, providing a robust and reliable foundation for RF applications. The use of thin film technology further enhances the performance of these filters, allowing for precise control over their characteristics.

Printed on this ceramic substrate, the RF thin film filters exhibit exceptional filtering capabilities in the microwave frequency range. This makes them indispensable for applications requiring high-frequency precision and reliability. The compact nature of these filters, coupled with their surface mount design, makes them an excellent choice for modern electronic circuitry.

The alumina thin film filters, with their advanced design and manufacturing techniques, cater to the demands of industries where efficiency, reliability, and miniaturization are critical. Whether incorporated into communication devices, sensors, or other RF-dependent systems, these filters stand out as versatile components that contribute to the advancement of small, high-performance electronics.

ECHO is developing Elliptic Filters, especially for high frequency bands up to 20GHz. We already have good filter solutions such as Ceramic (MONO/ Discrete), LC and SIW(Substrate Integrated Waveguide), but we are expecting that the Elliptic filter will be a good solution between 8GHz and 20GHz. The Elliptic Filter not only can generate a wider passband but also have steeper roll-off characteristics than Chebyshev and SIW filters. So, it can be one of our good filter solutions according to our customer’s various needs.We can offer the surface-mount and connectorized designs in a small size and at low cost compared to cavity or waveguide filters.

- Frequency range up to 20GHz
- Steeper Rolloff Characteristics than Chebyshev and SIW filters
- Surface Mount and Connectorized Design Available
- BPF/ LPF/ HPF/ DPX
- Small Size and Cost Effective Solution
- Power handling up to 10W
