The information will be aimed specifically at the use of the delay line mounted on a M/A-COM test sample board. The same theory and control scheme can be applied directly to the component by itself. This product allows the insertion of a variable electrical delay between its two ports. The control consists of four complimentary bit pairs (8 bits total). Each pair is given a different letter, as shown in the table to the right:. Delay Line 50 ps 100 ps 200 ps 400 ps Rev.

The hex and decimal representations are included for programming purposes. “1” denotes 5 volts and “0” denotes 0 volts. A given delay line is set when bits 2 and bit 1 are set to 0 and 1 respectively. The given delay line is bypassed when the bits 2 and 1 are set to 1 and 0 respectively. The “GND” pin on the test board header must be connected to the DC supply ground. 3 ADVANCED: Data Sheets contain information regarding a product M/A-COM Technology Solutions • North America Tel: 800.366.2266 / Fax: 978.366.2266 is considering for development.

For taking S-Parameter data, perform a standard calibration and measure the parameters for the given state. Below is a description of how to see the delay accurately. M/A-COM recommends the following measurement procedure: Set the delay line to the reference or insertion delay state. With the two ports of the VNA connected to the “in” and “out” on the test board, measuring S21, set display memory, and display data/memory. This will normalize your data to the reference insertion state. Next, switch the measurement format to phase. This should be flat and zero due to the normalization. Switch in the first delay line. (50ps). The display will not remain on zero, but will have an offset. Under the Scale/Reference menu, select electrical delay, and dial that up until the data reads zero again, across the band of interest. That electrical delay will be 50ps. Continue to switch in the delay lines, dialing in more delay each time. Other methods are possible, but this straightforward approach. We do not using the ‘delay’ format in the VNA. method of measuring this results response, and is less accurate than outlined above. is the most recommend The VNA’s in a noisy the method Rev. V3 Upon request, M/A-COM can provide a test control board to ease stepping through the states. 6 ADVANCED: Data Sheets contain information regarding a product M/A-COM Technology Solutions • North America Tel: 800.366.2266 / Fax: 978.366.2266 is considering for development.
