Company founded
1989
April Instrument was founded in 1989 to bring portability to the microwave signal generator field. Changes in microwave components allowed this to happen including the advent of MMIC's ( monolithic microwave integrated circuits ) which made possible a new level of miniaturization at reduced cost. Our first product was the model 8001 which was introduced in the November, 1989 issue of "Microwaves & RF" magazine. This unit weighed in at a tiny 2.5 lb. It was soon followed by the model 8002 which extended the frequency range of the 8001 from 2-8 to 2-10 GHz.
