Title :
2noscillators combined with 3-dB directional couplers for output power summing
Abstract :
A method of combining 2nidentical oscillators with 2n- 13-dB directional couplers for output power summing is described. Preliminary experimental results obtained at about 19 MHz with 32 tunnel diode oscillators and lumped constant 3-dB directional couplers show that the output power is multiplied by approximately 32.
