摘要： A method and electronic circuit for changing the gain of a radio frequency signal. The apparatus is an electronic circuit comprising one or more variable gain electronic elements, and one or more adjustable phase shifting elements. The method comprises the steps of receiving a radio frequency signal, varying the gain of the variable gain electronic element while the variable gain electronic element changes the amplitude of the radio frequency signal, and adjusting an adjustable phase shifting element to generate a reverse phase shift in the radio frequency signal in response to the associated phase shift from the step of varying the gain.

摘要： A system and method for frequency reuse for wireless point-to-point backhaul. Frequency reuse is enabled through the cancellation of interfering signals generated by interference sources. In one embodiment, a conventional dish antenna is complemented with one or more additional auxiliary antennas (e.g., isotropic). The one or more additional auxiliary antennas enable cancellation of interfering signals whose direction of arrival (DOA) is off the dish antenna's bore-sight.

摘要： A diversity receiver switch includes at least one second stage switch configured to communicate with a transceiver. The diversity receiver switch may also include at least one first stage switch coupled between a diversity receiver antenna and the second stage switch(es). The first stage switch(es) may be configured to handle a different amount of power than the second stage switch(es). The diversity receiver switch may include a bank of second stage switches configured to communicate with a transceiver. A first stage switch may be configured to handle more power than each switch in the bank of second stage switches. Alternatively, the diversity receiver switch include a bank of first stage switches coupled between the diversity receiver antenna and a second stage switch. The second stage switch may be configured to handle more power than each of the first stage switches.
