ABSTRACT:
An integrated bi-directional MMDS/MDS converter connected to an antenna for receiving MMDS programming for receiving information/data signals from a set top for retransmission of these signals back to central location. The integrated bi-directional converter has a down converter connected to the diplexer for down converting conventional programming signals into a group of converted programming signals in the 222 to 408 MHz range, an up converter for up converting data/information signals in the 116 to 128 MHz range from the communication line into MDS signals and delivers it into the diplexer. The diplexer applies the outgoing MDS data signals to the feed of the antenna for transmission. The integrated bi-directional MMDS/MDS converter of the present invention uses a common local oscillator for driving both the down converter and the up converter.
