ECHO Microwave

ECHO Microwave provides ceramic filters, duplexers and multiplexers from 100MHz to 12GHz. These are suitable for both commercial (e.g. TETRA, LTE, GSM, DCS,UMTS,GPS, set top box at 75 ohm) and military applications (e.g. S-band, C-band systems). Our ceramic filter products provide a compromise between cavity and lumped element designs, by offering high performance in a small size and at low cost. The high quality factor, "Q", of our devices ensures low insertion loss and high temperature stability. All ceramic devices can be customized for specialized mounting configurations and input/output connector types and we offer both leaded and surface-mount manufacture. High power products are specified to 20W.Performance and reliability are our top priorities. ECHO Microwave's design and manufacturing processes are subject to rigorous quality assurance procedures,which differentiate our products from those of our competitors. All of our ceramic devices come with a 2-year guarantee and are RoHS compliant.

ECHO Microwave's cavity filters, duplexers and multiplexers are available over the frequency range of 100MHz to 25GHz. These components provide low insertion loss, steep skirt selectivity and narrower bandwidths than ceramic filter solutions. ECHO Microwave provides cavity devices manufactured to customer specifications including for low passive intermodulation, which is important for WiMAX, LTE, CDMA and PCS systems. The high performance of our cavity filter products is driven by our careful selection of materials and specialized design topologies and sizing. High "Q" DR-Puck resonators can be implemented to achieve both low insertion loss and high band-edge rejection. Our products are suitable for fixed and mobile applications in the VHF, TETRA, LTE, GSM, DCS, UMTS and GPS bands and for both commercial and military satellite networks in the S,C,X and Ku bands. ECHO Microwave offers a custom design capability with up to 12 frequency bands being used for demanding customer requirements. Quality is our top priority and our design and manufacture is subject to rigorous internal auditing and testing. All of our cavity filter products are guaranteed for 2 years and are RoHS compliant.

ECHO Microwave's LC Filters(Lumped Element) are available over the frequency range of 5MHz to 10GHz. These products offer small size and high performance. As per our other filter devices, our LC designs can be individually customized to meet specialized requirements and input/output connector configurations, in addition to standard packages. Lumped element designs are best suited for applications where size and weight are critical. Our filter engineers are experts in Lumped Element design techniques and use a number of innovative methods to meet today’s demanding specifications. In addition, we provide LC diplexers with High-Q value and we can design it with high power up to 200W.

ECHO Microwave has developed a new filter by using substrate integrated waveguide which can be synthesized on a planar substrate and usually called SIW Filters. This filter generates via-holes on PC Board to make the waveguide and it makes easy to connect with other circuits. This concept is attractive for filter design, because it is helpful to reduce the size compared to existing filters such as ceramic and lumped filters. It is possible to make the SIW filter from 8GHz to 40GHz, but the SIW filter has a strong advantage for high frequency bands. We use the materials for the SIW Filter that has small values of Dissipation Factor which has 0.0009 value at 10G. So, it has high-Q factor and very low insertion loss. In case of ceramic and LC filters, it is not easy to apply the frequency ranges over 10GHz,but the SIW filter is available up to 40GHz and it is possible to generate the broad bandwidth. We can offer the surface-mount and connectorized designs in a small size and at low cost compared to cavity or waveguide filters. The size is very smaller than cavity products, but it has high performance and it can endure high power up to 50W.

ECHO Microwave offers isolators and circulators in standard packages across a frequency range of 400MHz to 10GHz. Both drop-in and connectorized designs are available.

ECHO Microwave manufactures customized low and high-power Wilkinson dividers and combiners that operate across our standard frequency ranges as below. - 88 to 960MHz / 380 to 2700MHz / 698 to 2700MHz/ 2000 to 8000MHz / 2000 to 18000MHz In addition to these product ranges
