hello all,
I simulated balanced amplifier and found the total output power decreased 6dB when one amplifier is bad, but, some aiticles say that it's 3dB not 6dB will decreased.
I use two 3dB hybrid couplers, two same amplifiers and one outputs 30dBm,the total output power of the 2nd hybrid coupler is 33dBm. It's right. BUT, when i set one amplifier's gain to -100dB and the total output power is 27dBm which means 6dB decreased.
Thanks.
