Bipolar: Designed for power amplifier applications in industrial, commercial and amateur radio equipment to 30 MHz. Silver Eagle 200 Amplifier Review. I picked up this amplifier because I was looking for a small amp to run on the base for a couple of months when I was running a temporary setup and I had to limit my output power at the time. The Silver Eagle 200 is a very simple and compact little amplifier. LINEAR AMPLIFIERS FOR MOBILE OPERATION Prepared by: Helge O. Granberg RF Circuits Engineering INTRODUCTION The three versions of the amplifier described here are intended mainly for amateur radio applications, but are suitable for other applications such as marine radio with slight modifications. 100 W is obtained with two MRF455’s. MRF460 or Until recently I had not played with or had anything that used MOT transistors other than my single President Lincoln which is a pussy-cat and does not push the MRF455 it uses hard at all. That combined with only having a single MRF455 I really did not worry about hfe or matching them etc....

Subject: Replacement transistors for the MRF 455 finals Hello Plowboy! I,ve been looking at some older "footwarmers" that have blown MRF 455 NPN final transistors in them. Can you use the SD1446 as drop-in replacements??? There are many (MRF455) type amps out there.... My little mobile amp uses 2 of the 1446 transisters. Been using it a while now with no problems and always get good reports. My 148 swings 20 watts with strong modulation into it and is really pushing the amp to its limits.
