Patent ID: 8805274

Claim:
An apparatus comprising: a power supply operative to provide an operating DC voltage for a low noise block (LNB) converter in a legacy mode of operation, said power supply exhibiting a low output impedance to a reference potential; a DiSeqC encoder and decoder coupled to said power supply operative to generate a control tone for communicating to said LNB converter in said legacy mode of operation; a transceiver coupled to an output point including a protection circuit operative to bi-directionally communicate with a frequency translation module; and a switching device including first and second transistors coupled between said output point and said power supply operative to couple said power supply to said output point in said legacy mode of operation and to decouple said power supply from said output point in an FTM mode of operation so that an FTM carrier generated by said transceiver may not be distorted by said low output impedance of said power supply.
