"John R. Strohm" wrote in message ... "Alfred Lorona" wrote in message ... Most mixers I've seen are not matched to 50+j0. They are simply terminated in 50+j0. Is this the best or optimum termination or does it matter? There is no "best" or "optimum" termination, beyond the fact that you want a purely resistive termination. (DUH!). 50 ohms is just the standard value. That *may* be true, but most mixers are characterized with 50 ohm (resistive) terminations at all ports. Use other impedances at your own risk! 73, John - K6QQ |
