Model: SFB-4G18G-5-CD-SFF-SP3T

Model SFB-4G18G-5-CD-SFF-SP3T has three switchable input channels which all pass through a common high pass output filter. The high pass filter offers a passband of 5.35 to 18.0GHz while rejecting frequencies from DC to 4.94GHz by greater than 48dBc. This model includes an integral TTL driver and offers fast switching speeds of less than 50nsec. Phase and Amplitude matching is available.
