Suspended Substrate Stripline Filters and Multiplexers 50 DC to 26 GHz The Big Deal Low insertion loss Ultra-wide passband width Fast roll-off with wide stopband Good power handling and temperature stability Passband up to 26 GHz Stopband up to 26.5 GHz can extend to 40 GHz Product Overview Mini-Circuits Suspended Substrate Stripline filters offer low insertion loss by implementing printed circuit board suspended between two parallel ground planes, providing high Q. Low insertion loss combined with wide stop- band makes them an excellent choice for wideband instruments and systems like ECM, ECCM, ELINT and ultra- broadband receivers. Low pass, high pass, band pass, band stop, diplexer and multiplexer designs can be realized with this technology. Advanced filter design and construction can achieve stopband width greater than 6x the center frequency, and tem - perature stability will be better than other printed circuit realizations because the fields are mainly in the air rather than in a dielectric. The inside walls of the housing hold the circuit and prevent movement that could be caused by vibration or mechanical shock, making these designs excellent candidates for harsh operating environments. Suspended substrate stripline filters can be realized in small form factors with high-quality, precise machining for applications where size is critical. Excellent repeatability across units is achieved through precise tuning and pro- cess control. Key Features Feature Advantages Low signal loss results in better SNR in receiver front end and better power delivery to antenna in Low insertion loss transmitters Fast roll-off Higher selectivity results in better adjacent channel rejection and dynamic range Wide stopband Wide, spur-free stop band results in better receiver sensitivity High power handling Well suited for transmitter applications Excellent temperature stability Ensures minimal variation in electrical performance across temperature Notes A.
