[1000mp] FW: [Yaesu] Pin diode mod. FT-1000 Ron

Mon, 02 Dec 2002 20:20:35 -0800

Constantine and group members,

The Motorola-designed MRF422 power devices used in the FT-1000/D PA are
still available. Although Motorola exited from the RF power device product
line, M/A-Com has picked up the production.

The MRF422 is in the RF Parts on-line catalogue. http://www.rfparts.com/

I also checked Future Electronics, and they show the MRF422 as "In Stock".
http://www.future-active.com/ search on "MRF422"

Also, the SGS-Thomson SD1729 is a cross, per their Power RF cross-reference.

A Google search on "MRF422 " was the source of this information.

Best 73,
