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

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
