High Power Bandpass Filter: P/N 91122A-1
Overview
P/N 91122A-1 is a right-angle transition version of the 60661A-3 JTIDS/MIDS high power bandpass filter. This unique drop-in device incorporates our traditional high power evanescent mode bandpass design with an additional coaxial notch at 944 MHz to ensure compliance with demanding CS04 test requirements. The filter is as small as can be when considering the combination of high power performance and low insertion loss. The unit is gold flashed for materials compatability in drop-in applications.

Band Rejection Filter: P/N 50151B-2
Overview
Low-Loss High Rejection Bandstop Filter
Overview
Used for rejection of MIDS/JTIDS, this is a bandstop design of a new type, offering very wide stopbands combined with passbands significantly wider than any previously available. Similar broadband designs are available for rejection of other radar and communication bands. These filters can be combined with switches to form receiver protection systems, reducing or eliminating broadband receiver desensitization issues in large-signal cosite scenarios.

Band Rejection Filter: P/N 61703B-3
Overview
JTIDS/MIDS Band Rejection Filter
This P/N 61703B-3 is the latest in the RS Microwave Band Rejection filter designed for resolving cosite interference problem with the JTIDS/MIDS Band. This filter has very steep transition slopes from passband to stopband (6 MHz is typical.). The unit is constructed as an elliptic air-slab line design, achieving high unloaded Q, which minimizes the insertion loss while maximizing the stopband attenuation.
