Abstract: The dual mode amplifier network for radiotelephone of the present invention has a first path (110) to be used in the U.S. Digital Cellular mode, and a second path (120) to be used in the FM analog cellular mode. The first path (110) has a first switch (106) coupled to the network input and to an isolator (103). A second switch (107) couples the isolator (103) to the network output. A third switch (108), in the second path (120), couples the network input to a filter (104). A fourth switch (109) couples to the filter (104) to the network output. A controller (130) closes the first switch (106) and the second switch (107) and opens the third switch (108) and the fourth switch (109) in the U.S. Digital Cellular mode. In the FM analog mode, the controller (130) opens the first switch (106) and the second switch (107) and closes the third switch (108) and the fourth switch (109).

Abstract: The dual mode power amplifier apparatus of the present invention is comprised of a number of power amplifiers (101-103) coupled to a voltage convertor (104) through their collector supply lines. A mod e select line (105) is connected to the voltage convertor (104) to select a digital or analog mode. The preferred embodiment of the present invention is used in a hybrid digital/analog radiotelephone in the digital mode, the voltage convertor (104) is turned off an d the voltage convertor (104) supply voltage is allowed through to the collectors of the power amplifiers (101-103). This permit s the power amplifiers (101-103) to operate with optimum linearity in a digital transmission environment. In an analog environme nt, the voltage convertor (104) is on and supplying a reduced voltage to the power amplifiers (101-103) allowing more effi cient operation in this mode.

Abstract: A dual mode power amplifier operable in etiher the linear mode or the saturation mode. The power amplifier, when comprising a portion of a radio transmitter, permits efficient amplification of either a frequency modulated or a composite modulated signal by operation of the amplifier in the saturation mode or the linear mode, respectively. A processor determines the modulation-type of the signal and generates a signal to cause operation of the amplifier in either the saturation mode or the linear mode.

Abstract: The dual mode amplifier network of the present invention enables a radiotelephone to operate efficiently in both the U.S. Digital Cellular mode and the FM analog cellular mode. Multiple, switched branches (110 and 120) permit one branch (110) with an isolator (103) to be used in the in the U.S. Digital Cellular mode while the other branch (120) is switched out. In the analog mode, the transmit filter branch (120) is used while the isolator branch (110) is switched out.

Abstract: CE00093R An integral phase shifting network of a transmitter filter provides a means to reduce the size and increase the efficiency of an antenna coupling network. The network to shift the phase of the transmitter filter is printed by depositing conductive material directly on a ceramic block using low-loss circuit elements and can be tuned easily by removing conductive material if required in certain applications. By utilizing an integral phase shifting network, either transmit or receive filters having a highly reactive and capacitive out-of-band impedance in the receive or transmit band, respectively, can be connected to a common antenna port without external transmission lines.

Abstract: A transmitter (604) of a TDMA cellular telephone (600) includes power control circuitry (100) comprised of variable gain stage (104), mixer (106), bandpass filter (109), RF amplifier (110), and directional coupler (112) in a forward path, and two detectors (116 and 117), four A/D converters (118, 119, 121 and 123), digital controller (120), and D/A converter (126) in a feedback path. In operation, the variable gain stage (104) is responsive to a gain control signal AOCCNT (128) for adjusting a modulated IF signal, which is then mixed in mixer (106) with an RF reference signal to produce the transmit RF signal. The temperature and supply voltage are sampled by controller (120) at the beginning of each time slot. Adjustments in the gain control signal (128) dictated by the sampled temperature and supply voltage are made by controller (120) in each time slot prior to keying the RF amplifier (110). The transmit RF signal is amplified by the RF amplifier (110) to produce the transmit output signal which is coupled by the directional coupler (112) and transmit filter (618) to an antenna (620) for transmission The forward power and reverse power of the transmit output signal are sampled by controller (120) at the end of each time slot. The sampled forward power is used by controller (120) in calculating the value of the gain control signal for the next time slot. If the sampled reverse power or supply voltage exceed respective maximum values, the RF amplifier (110) is dekeyed by controller (120).
