M/A-COM 1011 Pawtucket Blvd. Lowell, Massachusetts 01853 UNITED STATES Phone: 978-442-5000 Fax: 978-442-5350 For RF/Microwave Products, contact us at: Americas -- Phone: 1-800-366-2266 http://www.macom.com/psc/jsp/SearchParts.jsp - came up blank on the part number. Judging by the name still being Microwave Associates, you're going to have to find an old-timer to figure out what that thing is. Nate WY0X
