Abstract:
1. A circuit, comprising: a first node configured to receive a signal that includes low frequency components between approximately zero hertz and one-half of a symbol rate of the signal and high frequency components that are between approximately one-half of the symbol rate and the symbol rate of the signal, wherein at least one of the high frequency components is equal to the symbol rate of the signal; a first path coupled to the first node and configured to receive the signal from the first node and to output a first path signal based on the signal, the first path including an amplifier configured to amplify all of the high frequency components of the signal received from the first node; a second path coupled to the first node and configured to receive the signal from the first node, to amplify the low and the high frequency components of the signal, including the at least one of the high frequency components that is equal to the symbol rate of the signal, and to output a second path signal based on the amplified signal, the second path being a single path that is not formed by parallel paths; a data circuit outputting the signal received by the first node; and a second node coupled to the first path and the second path and configured such that the first path signal and the second path signal combine at the second node.
