Assignee: PAGNANELLI FAMILY TRUST
Field: Basic communication processes (Electrical engineering)
Classification: CPC H | IPC G  H

Claim 0:
1. An apparatus for converting digital data to radio-frequency (RF) signals, said apparatus comprising:
an input line for receiving binary-encoded data samples;
a decoder having: an input that is coupled to the input line and a plurality of outputs which provide binary waveforms based on the data samples;
a reactive-impedance network having an output and comprising a plurality of segments, with: (a) an input of each of said segments coupled to a different one of the outputs of the decoder, (b) each of said segments including at least one shunt capacitive reactance and at least one series inductive reactance, with the series inductive reactance implemented as a discrete element, and (c) said segments also including active devices; and
an output line that is coupled to one end of said reactive-impedance network,
wherein said active devices of said reactive-impedance network differently boost signals derived from said decoder outputs, based on a binary-encoding technique across said binary waveforms,
wherein said reactive-impedance network contains a number of capacitive elements that is greater than or equal to the number of said active devices, and
wherein signals derived from decoder outputs are combined within said reactive-impedance network to produce a single, composite signal at said output of said reactive-impedance network.
