Transmitter architectures for communications systems

Abstract From the Canadian patent

Transmitter architectures for a communications system having improved performance over conventional transmitter architectures. The improvements include a combination of the following: faster response time for the control signals improved linearity, reduced interference reduced power consumption, lower circuit complexity and lower costs. For a cellular application these improvements can lead to increased system capacity smaller telephone size, increased talk and standby times and greater acceptance of the product. Circuitry is provided to speed up the response time of a control signal. The control loop for various elements in the transmit signal path are integrated. A gain control mechanism …
