ABSTRACT:
The present invention provides an RF transmitter network for cellular telephone systems. The network includes power amplifier circuitry which coupled to a closed loop control system to provide a controllable RF amplitude envelope for the output power of the amplifier circuitry over a dynamic range of between about 5 milliwatts and about 3200 milliwatts.
