Method, system, and apparatus for a differential transformer-free hybrid circuit

摘要

A differential transformer-free hybrid circuit includes a first amplifier configured to receive a first signal from a transmitter and output the first signal to a telephone loop, and a second amplifier configured to receive a second signal from the telephone loop and output the second signal Io a receiver Further, the differential transformer- free hybrid circuit also includes at least one balanced network element and a trans former-less interface configured to couple the first amplifier and the second amplifier to the telephone loop, wherein the transformer-less interface includes at least one current blocking device.
