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.
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.
MtronPTI’s UF9382 is a high bandpass cavity filter with less than 1.5 dB passband attenuation designed to operate in applications with temperatures ranging from -40°C to +85°C. The filter features a passband range of 9.820 GHz – 9.970 GHz, and an insertion loss less than 2.2 dB.
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.
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 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.
Corry Micronics offers the CMIINV-5BT2-RM cellular band switched filter module with optional switched amplification for monitoring the transmit or receive Band 1, Band 2, Band 5, Band 13, and Band 17 cellular signals. Features include high out of band rejection specifications, high band to band isolation of 50 dB minimum, low noise figure, and standard 50 ohm impedance.
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).
