In this picture, the photodiode array is irradiated from the communication system's LED and then it would convert the light signals on the broadcast band. The circuit is similar with the 1:1 balanced-unbalanced converter and it has the single-channel input and double-channel output. The phase-shifting between the two output is 90°. The circuit would not require neutralization. It can give reasonably the high gain with low noise response.
