Tunnel diodes with peak currents of 35-75 ma were tested in coaxial circuits with load impedances varied from one to eight ohms. The best results to date were obtained with a 50 ma diode and a load impedance of one ohm. This diode gave 2.0 mw at 7.9 Gc, which is close to the theoretically calculated power output of 2.5 mw at 8.5 Gc. It is expected that minor changes in the circuit will yield between 2.0 and 2.5 mw of rf power at the design frequency of 8.5 Gc. Circuits utilizing the parallel operation of diodes have been designed and are presently being constructed. Author
