Abstract:
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.
