Frequently Asked Questions (FAQ)
for Terminations & Mismatches
|
| 1) What is the difference between a Termination and a Mismatch? |
| A termination properly loads a transmission line to reduce reflections. Mismatches are used to create reflections for testing purposes. Here are some examples: 50 Ohm termination: 50 Ohms to ground from the center pin.
50 Ohm 1.5:1 mismatch: 75 Ohms to ground from the center pin.
50 Ohm 2.0:1 mismatch: 100 Ohms to ground from the center pin.
50 Ohm 10.0:1 mismatch: 500 Ohms to ground from the center pin. |
|
| What is the XXX in mismatch model numbers used for? |
| The XXX is used to list the mismatch value. Here are some model number examples: 50T-338-1.0 N M 1.0:1 termination with N male connector 50T-338-1.5 BNC M 1.5:1 mismatch with BNC male connector 50T-338-2.2 SMA F 2.2:1 mismatch with SMA female connector |

| 3) Do you have any high peak power terminations? |
| Yes, we just don't have them in our catalog. Models are available that handle up to 20 KW pulses. Please contact JFW at sales@jfwindustries.com with your specific pulse width, duty cycle, and period. |
|
| 4) I need a custom termination designed. How much are your typical NREs (non-recurring engineering charge)? |
| JFW does not charge NREs. Please send your custom requirement to sales@jfwindustries.com. |
