Are You really Naive ?
DDX is for AUDIO, not rf ( http://www.apogeeddx.com/apogee_ddxtech.html )Class T amps are possible competition ( http://www.tripath.com/tech.htm ), but they also are concentrating on non RF amplifiers at this point.However, there is absolutey no no competition for the Vector version of the amplifier that directly takes baseband inputs and outputs an amplified, on channel RF signal.PRKR will offer a superior amplifier at the same price and form factor as the OEMs current amps. Should be an easy decision.
Crj ,can we discuss ? I am not saying Parker has not done a significant advance . I'm simply trying to Understand ? Please explain.
