Patent number: 10312878Abstract: Systems and methods for switching on and off a power amplifier including a signal input receiving an input signal and a signal output providing an output signal. The power amplifier includes a control input receiving a gain control signal indicating a requested gain and a control input receiving a mute control signal indicating whether the signal output should be switched on or switched off. A control unit determines whether the signal output of the power amplifier should be switched on and/or off, and if switched on receives data identifying a switch-on ramp and if switched off receives data identifying a switch-off ramp. The control unit generates the mute control signal to switch on the signal output of the power amplifier on or off, and generates the gain control signal as a function of the data identifying the switch-on or switch-off ramp to thereby increase or decrease the gain control signal.Type: GrantFiled: May 31, 2017Date of Patent: June 4, 2019Assignee: STMicroelectronics S.r.l.Inventors: Angelo Scuderi, Gesualdo Alessi, Antonino Calcagno, Giorgio Maiellaro, Salvatore Scaccianoce

Patent number: 9257996Abstract: An oscillator circuit may include a local oscillator to generate a carrier signal having a tunable frequency, a first modulator and a power amplifier coupled in cascade to the local oscillator to generate an output signal. The first modulator may be activated from a first modulating signal having a first frequency alternatively defining ON and OFF states of the first modulator. An estimator unit may receive the carrier signal during a time window and detect an estimated frequency variation of the carrier signal during the ON and OFF states. A compensation unit may include a second modulator to generate a compensation signal proportional to the estimated frequency variation and modulated with a second modulating frequency. The second modulating frequency may be substantially the same as the first modulating frequency, and the compensation signal may be added to a bias signal of the local oscillator to tune the tunable frequency.Type: GrantFiled: June 17, 2015Date of Patent: February 9, 2016Assignee: STMICROELECTRONICS S.R.L.Inventors: Angelo Scuderi, Antonino Calcagno, Salvatore Scaccianoce

Patent number: 7358807Abstract: A protection method may prevent a load-mismatch-induced failure in solid-state power amplifiers. In an RF power amplifier, the load voltage standing-wave ratio results in very high voltage peaks at the collector of the final stage and may eventually lead to permanent failure of the power transistor due to avalanche breakdown. The method avoids breakdown by attenuating the input power to the final stage during overvoltage conditions, thus limiting the output collector swing. This is accomplished by a feedback control system, which detects the peak voltage at the output collector node and clamps its value to a given threshold by varying the circuit gain. Indeed, the control loop is unlocked in the nominal condition and it acts when an output mismatching condition is detected. A control circuit also allows a supply-independent collector-clamping threshold to be accurately set.Type: GrantFiled: February 24, 2006Date of Patent: April 15, 2008Assignee: STMicroelectronics S.r.l.Inventors: Angelo Scuderi, Antonino Scuderi, Luca La Paglia, Francesco Carrara, Giuseppe Palmisano
