For demanding aerospace and defense applications, MCV Microwave offers an extensive line of LC filters in surface-mount, drop-in and “connectorized” packages that withstand rugged environments. LC filter configurations comprise lowpass, highpass, bandpass, band reject, duplexers, multiplexers and tunable filters, with center frequencies from 100 kHz to 10 GHz.

MCV Microwave has developed three new filter families for wireless infrastructure. The first is a line of ultra-low passive intermodulation (PIM) cavity filters and multiplexers covering the TETRA and all LTE frequency bands from 300 to 3600 MHz. The typical production PIM performance is −163 dBc, measured with two CW tones, each at 43 dBm. An even lower PIM filter line with a guaranteed −173 dBc is available for PIM test bench and more demanding testing applications.

High performance frequency selective surface (FSS) filters have a myriad of applications in the field of 5G wireless communication and antenna/radome systems. The most common FSS is a two-dimensional (2D) periodic array of thin conducting or aperture (also termed slot) elements etched on a flat or curved dielectric structure. This type of structure usually exhibits frequency filtering characteristics similar to the frequency filters in traditional RF circuits.

MCV Microwave has developed a line of ultra-low passive intermodulation (PIM) cavity filters and multiplexers covering frequency bands from 250 MHz to 6 GHz. The typical PIM performance in production is -163 dBc measured with two CW tones, each at 43 dBm. An even lower PIM filter with a maximum of -168 dBc is available, if requested.
