Abstract: A wireless communication device is described. The wireless communication device includes a transmit/receive (T/R) switch that is configured with an antenna port coupled to an antenna, a transmitter port coupled to a transmitter and a receiver port coupled to a receiver. The T/R switch selectively connects the transmitter port to the antenna port or the receiver port to the antenna port. The wireless communication device also includes a T/R switch controller that sets the T/R switch to disconnect the transmitter from the antenna when the transmitter is actively transmitting in a high insertion loss mode to reduce power from the transmitter to the antenna.

Abstract: A method for communications is described. The method includes determining a symbol timing drift elimination amount for a received signal. The method further includes eliminating part of the symbol timing drift by adjusting a reference clock for the modem. Determining the symbol timing drift elimination amount may be based on at least one of a symbol timing drift estimate, a symbol timing error, a packet acquisition indicator, a packet validity indicator, demodulated bits or a carrier presence indicator.
