Filter Topologies
cavity filters Cavity Filters
These TEM mode filters consist of inductively coupled short circuited stub resonators. Cavity filters are high Q structures for high selectivity, with very low passband insertion loss, which is important for receiver front end or high power transmit applications.		 ceramic filters Ceramic Filters
Spectrum Microwave integrates Low Pass Filters into the designs for Ultimate Rejection Optimization. A Temperature Stabilizing Sponge can be utilized for harsh environments.
lumped elements Lumped Elements
Lumped element filters consist of discrete capacitors and inductors soldered to a substrate in various schematic configurations. These compact designs are particularly suitable for applications where size is critical.		 tubular filters Tubular Filters
Spectrum Microwave tubular filters provide relatively high unloaded Q’s in a moderate package size. Due to their mechanical configuration, tubular filters have inherently broad stopbands with very high attenuation levels.
waveguide filter Waveguide Filters
Waveguide bandpass filters consist of half wavelength resonant cavities coupled by capacitive or inductive irises. These extremely high Q structures provide very low passband loss and steep attenuation skirts.		 suspended substrate Suspended Substrate
Suspended substrate have an increase is unloaded Q which results in lower passband loss than conventional stripline filters. In addition, the lack of dielectric surrounding the circuit makes the filter less sensitive to ambient temperature variations.
