MIL-D-23859C

The 1518-series device is a fixed, single-input, fiveoutput, passive delay line. The signal input (IN)of MIL-D-23859C is reproduced at the outputs (T1-T5) in equal increments. The delay from IN of MIL-D-23859C to T5 (TD) and the characteristic impedance of the line (Z) are determined by the dash number. The rise time (TR) of the line is 30% of TD, and the 3dB bandwidth is given by 1.05 / TD. The device is available in a 14-pin SMD with two pinout options.

Part numbers of MIL-D-23859C are constructed according to the scheme shown at right. For example, 1518-101-500A is a 100ns, 50W delay line with pinout code A. Similarly, 1518-151- 501 a is 150ns, 500W delay line with standard pinout.
