FUNCTIONAL DESCRIPTION
The 1515-series device is a fixed, single-input, single-output, passive delay
line. The signal input (IN) is reproduced at the output (OUT), shifted by a
time (TD) given by the device dash number. The characteristic impedance
of the line is given by the letter code that follows the dash number (See
Table). The rise time (TR) of the line is 10% of TD, and the 3dB bandwidth is given by 3.5 / TD.
SERIES SPECIFICATIONS
• Dielectric breakdown: 50 Vdc
• Distortion @ output: 10% max.
• Operating temperature: -55°C to +125°C
• Storage temperature: -55°C to +125°C
• Temperature coefficient: 100 PPM/°C
