This reminds me of two situations at Loral Corp. Back a long time ago Communications Transistor Corporation (CTC) made some of the best high UHF and low microwave transistors around. Like Eimac they were a Varion (sorry spelling) owned company. They had a reliable and consistent product you could teach high school students to tune and build S-band 25W emitter driven power amplifiers. (I'm serious those parts and the design were that good) Well unfortunately TRW bought them out and lost the recipe......... There were a few months of hard times for us because good parts were few and far between, and one of your contracts calls for fifty-five complete high power (40W) S-band video transmitters every month..... The term for TRW was Trashy Radio Work for a time then until they got their act together. Well you know Motorola thought they were GOD's Gift to RF techonology and bought TRW's semiconductor division. Motorola's experience past 1.2GHZ was lacking for a time also. They couldn't make a good part to save their pitiful life for a time, but then finally got it right. Now I know we put TRW under a lot of pressure to preform after they bought CTC.... Every one of those high power video transmitters used five of one type of transistor and two of another in the stages following the VCO which used a Microwave Associates transistor. Just because another company starts to build a part doesn't mean it's going to be as good as the old part. It usually won't until or if they get their act together.
