Model: 7SFB-950M18G-CD-SFF      

PMI Model 7SFB-950M18G-CD-SFF is an eight channel switched filter bank that covers passband frequencies of 950MHz to 18.05GHz.  This filter bank offers 7 different passbands throughout the operating frequency which can be selected via a 3-Bit decoded TTL signal.  The eighth channel serves as a by-pass which will pass 950MHz to 18.05GHz from the input to the output.  All passband channel losses are equalized to be within 2dB of one another.  Switch speed is under 100nsec and VSWR is better than 2.0:1.  The housing measures 4.33" x 5.1" x 0.98".
