The CB503 tuneable High-Q, high power VHF/UHF bandpass filter is comprised of a three section passive machined combline filter with an input/output coupling structure. This coupling structure enables the filter to be tuned to any central frequency in the range of 160 MHz to 360 MHz while maintaining its high-Q and excellent rejection, insertion loss, and center return loss performance. This filter is ideal for de-confliction filtering, military mobile/mounted VHF/UHF communication systems, and base station antenna filter 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).
The Tusonix series of surface mount EMI filters are designed to have the highest current handling with the finest pitch in order to support the best board density for protecting systems with numerous parallel high-power lines. These high power filters occupy only 3.2 mm of PBC width, which is the narrowest in the industry for 10 A and 20 A rated filters.
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.
The ultra-miniature UB Series of lumped element filters from K&L Microwave are capable of operation in applications with frequencies ranging from 300 to 2500 MHz. These filters are available with 2 to 5 resonant sections, and bandwidths from 5% to 15% for ƒ0 < 1000 MHz, or 10% to 20% bandwidths for ƒ0 ≥ 1000 MHz.
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.
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.
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.
