Abstract
A radio frequency signal processing system such as an LMDS transceiver includes a receive switch, a first signal reception processing block, a second signal reception processing block, a transmit switch, a first signal transmission processing block, a second signal transmission processing block, and a controller to transmit the incoming radio frequency signal to a selected one of the first and second signal reception processing blocks, and causes the transmit switch to receive the outgoing radio frequency signal from a selected one of the first and second signal transmission processing blocks. Multiple frequency ranges may therefore be handled by a single LMDS transceiver, enabling low-cost mass production of the transceiver.
Claims6
A radiofrequency signal processing system comprising:
- a radiofrequency signal processing device having an input terminal and an output terminal;
- a DC blocking system having a quad arrangement of capacitive elements, the DC blocking system being coupled between a radiofrequency input signal source and the input terminal of the radiofrequency signal processing device;
- an RF filter system having a quad arrangement of capacitive elements, the RF filter system being coupled between the DC blocking system and a ground node;
- and
- a diode system having a quad arrangement of diode elements, the diode system being coupled in series with the DC blocking system between the radiofrequency input signal source and the input terminal of the radiofrequency signal processing device.
