1509-20C Datasheet PDF - Data Delay Devices

FUNCTIONAL DESCRIPTION
The 1509- and 1509J-series devices are mechanically variable, passive delay lines. The signal input (IN) is reproduced at the tap output (TAP), shifted by an amount which can be adjusted between 0 and TD, where TD is the device dash number. The fixed output (OUT) reproduces the input, delayed by TD, and must be terminated to match the characteristic impedance of the line, which is given by the letter code that follows the dash number (See Table). The tap output is unbuffered. The 3dB bandwidth of the line is given by 0.35 / TR, where TR is the rise time of the line (See Table).
