Knowles Precision Devices (DLI) offers filter technology that addresses the challenge of implementing high-performance filters at mmWave frequencies. Their 26 GHz, 28 GHz, and 39 GHz filter solutions deliver 3 GHz of bandwidth, greater than 50 dB rejection, and are 20x smaller than current alternatives while implemented in surface mount packages for standard tune-free assembly. They are capable of stable operation within the -55°C to +125°C temperature range. Custom design services are available.
As 5G testing continues to grow and demand more requirements for filtering components. Corry Micronics (CMI) has developed all types of filtering using different technologies, and several that have been allocated for 5G. At lower frequencies in the US market centered around 600 MHz, filtering can be easily, and cost competitively designed using several different filtering technologies. Types of filters range from LC to cavity, combline, interdigital, Helical, ceramic resonator, and tubular.
Corry Micronics, Inc. (CMI) offers a series of 52 GHz Waveguide Filters designed for operation in the 10 GHz to 60 GHz frequency range for cellular and satellite communication system, avionics communications, radar, and other high-power applications.
Qorvo offers the new QPQ1295 high-performance BAW filter specifically designed for Band 25 downlink. Features include low insertion loss, high attenuation, a 65 MHz bandwidth, and Pb-free, RoHS compliance.
Qorvo’s QPQ1907 is a high-performance, high power Bulk Acoustic Wave (BAW) band-pass filter designed to enable coexistence of WiFi and LTE signals within the same device or in close proximity to one another. This device is ideally used in WiFi/Bluetooth, consumer premise equipment (CPE), small cells, and smart meter applications.
MtronPTI offers the new Iridium Band Filter for aviation, maritime, land mobile, IoT, and military communications applications. These narrow bandwidth, high rejection band filters are designed to isolate Iridium frequencies from outside interference.
Corry Micronics has developed a lab grade filter module that passes the super speed USB3.1 at 10Gbps designed specifically for LTE band rejection. The CFM1-USB31-C and CFM1-USB31-AB are designed to pass data between USB 2.0, USB 3.0 and USB 3.1 devices at up to 10 Gbps while rejecting conducted and radiated interference and noise. These products are used with an RF shielded enclosure or shielded room to isolate products undergoing testing that require an electrically quiet environment.
MtronPTI incorporates RF CAD design and synthesis into their X and Ku band low profile cavity filters. These low-profile, laser-sealed filters are designed to not only reduce the overall mechanical footprint, but also offer improved electrical performance in space, SATCOM, EW and avionics applications.
