Microwave Associates (µA) MA-7530-PMD DC-18 GHz SPDT FAILSAFE 28V

exact item shown, coaxial switch by µA , Microwave Associates, date code is summer of 1980.  if you look at the test data, you can see that it's working ok on port 2 (normally open) but sometimes port 1 shows excess ripple, which tells me it probably has some contaminant on it - I've had good luck repairing these, but I'm not going to bother with this one, I'm short on time, so I've set the price at about 1/2 of what it would normally be - if you are only going to use the normally open (port 2) contact, then this switch is fully functional, if you need both ports, I think it will probably clean up just fine if you operate it a few thousand times (just hook it to a little pulse generator) - it got a lot better after actuating it for about 20 seconds back and forth.  If not, I think on these switches (it looks like it at least), you loosen the nut on the SMA connector and you can unscrew it and clean the contact on the connector with some alcohol or a soft cloth. Note to me: box with other coax switches I normally ship within 24 hours of your order, but the post office does not always initiate tracking when I put the packages in the drop off box. Check out my !
