    • A method for power control, including determining a need in a transmitter to perform a first output power update and then a second output power update. The method includes selecting a control mode for the first output power update and a control mode for the second output power update prior to performing the first output power update. The control modes are selected from a closed loop mode and an open loop mode, and the selection is based on a function of a current output power, a power to be applied at the first output power update, and a power to be applied at the second output power update. The method includes performing the first output power update using the first control mode, and then performing the second output power update using the second control mode, without measuring a power level applied responsively to performing the first output power update.

    • A transmitter includes a Power Amplifier (PA), an antenna, at least one passive component and control circuitry. The PA is controlled by a PA control voltage, is operative to amplify a Radio Frequency (RF) signal and has input and output amplifier terminals. The passive component has an input component terminal coupled to the output amplifier terminal of the PA and an output component terminal coupled to the antenna. The control circuitry is configured to determine an interim power level at the output amplifier terminal that causes the signal at the output component terminal to have a target output power level, to determine, based on the interim power level, a given PA control voltage that makes the interim power level producible by the PA, so that the signal at the output component terminal has the target output power level, and to apply the given PA control voltage to the PA.

    • A method includes holding in a memory of a receiver, for each temperature in a range of temperatures, a respective first parameter indicative of a frequency error of a crystal oscillator in the receiver at the temperature, and a respective second parameter indicative of an uncertainty of the first parameter. An operating temperature of the crystal oscillator is measured. One or more frequencies, for initial acquisition of signals from a transmitter, are selected based on the first and second parameters corresponding to the measured operating temperature. The receiver is tuned to receive the signals from the transmitter on at least one of the selected frequencies.

    • A method in a transmitter including a transmission chain and a Power Amplifier (PA), includes storing calibration data relating a plurality of specified output power levels of the transmitter to respective PA control voltages for application to the PA and respective gain levels for application to the transmission chain that cause the transmitter to output signals at the specified output power levels. A target output power level is specified, and an actual control voltage is applied to the PA. The actual control voltage is derived from a specified target control voltage depending on the target output power. A modified gain level which, when applied to the transmission chain while the PA is controlled with the actual control voltage, causes the transmitter to output the signals at the target output power level, is computed based on the calibration data. The modified gain level is applied to the transmission chain.
