Suspended Substrate stripline Diplexer, 50Ω, DC to 20000 MHz (DC-7500, 10500-20000 MHz)


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 stopband makes them an excellent choice for wideband instruments and systems like ECM, ECCM, ELINT and ultrabroadband 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 temperature 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 process control.


• Low passband insertion loss of 1 dB typical up to 20 GHz in highpass channel. • High rejection of 90 dB typical upto 20 GHz in lowpass channel. • Good return loss of 12 dB typical in all the channels.
