Teledyne Microwave Solutions offers a range of filters for defense and space applications. Filter types include electro-mechanical filters, fixed filters, fast tuned notch filters, and TDS bandpass filters.
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.
Qorvo’s QPQ1300 is a high performance bulk acoustic wave (BAW) bandpass filter specifically designed for sub band 41 (60 MHz BW) applications. Features include low insertion loss, high rejection, high attenuation, and a compact, RoHS compliant 5.00 x 5.00 x 0.93 mm packaging.
Teledyne Defense & Space (TDS) offers a range of fast tune notch filters (FTNF) that have been designed to protect Electronic Support Measures (ESM) receivers from high duty cycle, frequency agile interference produced by on board (or cohort) combat radar systems. ESM sensors need protection from high-level, long pulse and frequency-agile radars.
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.
NuWaves Engineering offers the NuFilter™ series of cavity filters designed for applications operating within the 1 GHz to 20 GHz frequency range. Options for standard and custom models include 3 dB bandwidths from 3% to 28%, stop-band rejections of 80 dB, insertion losses of < 1 dB, and up to 50 W power handling (higher power ratings available upon request).
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, 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.
