Abstract: 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 allows for accurate adjustment of the output transmit power level. Control mechanisms are provided to power down the power amplifier, or th e entire transmit signal path, when not needed. The gains of the various elements in the transmit signal path are controlled to reduce transients in the output transmit power, and to also ensure that transients are downward.

Abstract: Un procedimiento para ajustar la ganancia de señal en un transmisor con un primer elemento de ganancia y un segundo elemento de ganancia, en el cual el primer elemento de ganancia responde a un primer reloj de actualización y el segundo elemento de ganancia responde a un segundo reloj de actualización, en el que el segundo reloj de actualización es más rápido que el primer reloj de actualización y los relojes de actualización primero y segundo son asíncronos, comprendiendo el procedimiento: recibir un primer valor de configuración de ganancia para el primer elemento de ganancia y un segundo valor de configuración de ganancia para el segundo elemento de ganancia; generar una primera señal de control de ganancia, representativa del primer valor de configuración de ganancia; generar una segunda señal de control de ganancia, representativa del segundo valor de configuración de ganancia; alinear la primera señal de control de ganancia con el primer reloj de actualización, y ajustar la ganancia del primer elemento de ganancia en un primer momento de actualización; detectar un cambio en el valor de configuración de ganancia del primer elemento de ganancia; si se detecta un cambio en el valor de configuración de ganancia, alinear la segunda señal de control de ganancia con el primer reloj de actualización, para ajustar la ganancia del segundo elemento de ganancia en el primer momento de actualización; si no se detecta ningún cambio en el valor de configuración de ganancia, alinear la segunda señal de control de ganancia con el segundo reloj de actualización; ajustar una ganancia del primer elemento de ganancia con la primera señal alineada de control de ganancia; y ajustar una ganancia del segundo elemento de ganancia con la segunda señal alineada de control de ganancia.
