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.
MtronPTI offers a high power switched LC filter assembly designed to reduce the overall mechanical footprint, and improve electrical performance and power handling. These filters feature high power, reduced component count, better isolation, higher RF shielding, and low insertion loss.
MtronPTI offers a new family of L1 and L2 band ceramic filters that are ideally suited for industrial and commercial applications involving L1 and L2 GPS bands, and for use with L1 and L2 GPS receivers. Filters are manufactured using High-Q Ceramic Resonators to achieve low insertion loss.
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.
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.
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 now offers the CMIBPF-23G-2G, a new strip line bandpass filter with a center frequency of 23 GHz designed specifically as a lightweight filter for communication drones. This K-band filter is unique in that it features a surface mountable design, pick and placed characteristics, and installation with standard off the shelf solders.
Knowles Capacitors’ excellence in ceramic materials technology, combined with EMI filter expertise, has enabled Knowles (Syfer brand) to offer an unequalled range of EMI filter products including surface mount filters, panel mount filters, planar arrays, discoidal multilayer capacitors, X2Y integrated passive components, and other filter types for hi-rel applications.
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).
