FIXED SIP DELAY LINE
TD/TR = 5
(SERIES 1514)
FEATURES PACKAGES
• Fast rise time for high frequency applications
• Very narrow device (SIP package)
• Stackable for PC board economy
• Low profile
• Epoxy encapsulated
• Meets or exceeds MIL-D-23859C
FUNCTIONAL DESCRIPTION
The 1514-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 20% of TD, and the 3dB bandwidth is given by 1.75 /
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
