FUNCTIONAL DESCRIPTION
The 2020- and 2021-series devices are fixed, single-input, single-output,
passive delay lines. The signal input (IN) is reproduced at the output (OUT),
shifted by a time (T
D
) given by the device dash number. The characteristic
impedance of the lines is nominally 50 ohms. The rise time (T
R
) of the lines
is no more than 1ns, resulting in a 3dB bandwidth of at least 350MHz.

Network analyzer is used in phase measurement mode, normalized with a wire jumper between input and
output of DUT test socket. Delay is related to phase lag with proportionality constant of 100ps/deg.
NOTE: The above conditions are for test only and do not in any way restrict the operation of the device.
