2075/2075A FIXED HIGH B.W. DELAY LINE TR < 1ns (SERIES 2075 & 2075A) FEATURES • • • • • • • data 3 delay devices, inc. PACKAGES Microstrip Technology Fast rise time for high frequency applications Fixed delays available from 300ps to 6ns Mechanically variable delay available (2075A) I/O reversible BNC female connectors Meets or exceeds MIL-D-23859C IN OUT 2075-xx xx = Delay (TD) IN OUT 2075A FUNCTIONAL DESCRIPTION PIN DESCRIPTIONS The 2075- and 2075A-series devices are single-input, single-output, IN Signal Input (BNC) passive delay lines. For the 2075, the signal input (IN) is reproduced at the OUT Signal Output (BNC) output (OUT), shifted by a time (TD) given by the device dash number. The rise time (TR) of the lines is no more than 1ns, resulting in a 3dB bandwidth of at least 350MHz. For the 2075A, the delay is mechanically variable from 3ns to 7ns and the bandwidth is 6MHz. The characteristic impedance of both lines is nominally 75 ohms.
