“Method and Arrangement for Forming a Transmission Signal” describes a system for producing an amplitude- and phase-modulated transmission signal. Separate baseband signals control phase and amplitude: the phase-control signal drives a voltage-controlled oscillator, while the amplitude-control signal adjusts the RF amplifier. A sampled feedback signal is used to correct both controls and linearize the system’s transfer function. This approach is designed to support efficient nonlinear amplification while maintaining good phase and amplitude linearity.

“Dual Rate Power Control Loop for a Transmitter” concerns a radio-frequency transmitter power-control loop. A detector measures output power, and a controller supplies reference signals to a differential amplifier. A dual-rate filter adjusts how quickly the control signal reaches the power-control amplifier: it responds rapidly when reference signals change and more slowly during steady operation. This design enables fast power adjustment while supporting stable control.
