Abstract: A mobile wireless communications device may include a housing, a wireless receiver carried by the housing and configured to receive communication signals over a wireless frequency range, a wireline transmitter carried by the housing and configured to transmit communication signals overlapping in frequency with the wireless frequency range, and a controller carried by the housing and coupled with the wireless receiver and the wireline transmitter. The controller may be configured to determine when the wireless receiver is to begin receiving and, based thereon, switch the wireline transmitter to a suspended communication mode during which transmission is disabled. The controller may also be configured to determine when the wireless receiver has completed receiving and, based thereon, switch the wireline transmitter to a normal communication mode in which transmission is enabled.

Abstract: A communications device, in one aspect as a portable wireless communications device, includes an in-phase modulator and power amplifier that receives a baseband I signal and modulates and amplifies the I signal. A quadrature modulator and power amplifier receives a baseband Q signal and modulates and amplifies the Q signal. A power combiner sums and outputs the I and Q signals. An I demodulator circuit receives a signal fed back from the I power amplifier and demodulates the fed back signal to produce demodulated I signals. A Q demodulator circuit receives a signal fed back from the Q power amplifier and demodulates the fed back signal to produce demodulated Q signals. A processor compares the digital, baseband I and Q signals with a demodulated I and Q signals to compensate for amplitude, frequency and phase modulation errors.

Abstract: A mobile wireless communications device includes a housing, antenna, and circuit board carried by the housing and having radio frequency (RF) circuitry operative with the antenna for receiving and transmitting RF signals through the antenna. A power amplifier is connected within a transmission line for amplifying RF signals to be transmitted over the transmission line to the antenna. An antenna switch is connected to the antenna and RF circuitry. An RF shield surrounds the power amplifier and antenna switch and isolates the power amplifier and antenna switch from the antenna and RF circuitry. A low pass filter is connected to the power amplifier and antenna switch for reducing any RF coupling of voltage standing waves of upper harmonic frequencies from the power amplifier into the antenna switch through the RF shield while maintaining transmission of signals through the transmission line at a desired fundamental frequency.
