  • Patent number: 12113497
    Abstract: A dual-mode switchable power control circuit for an RF transmit signal path of an RF transmitter is switchable between an open-loop automatic gain control (AGC) mode and a closed-loop automatic level control (ALC) mode in the analog domain to provide power control for the RF transmit signal path. The open-loop AGC mode and the closed-loop ALC mode are both controlled based on the analog control signal on the same control line. In the open-loop AGC mode, the analog control signal corresponds to the AGC control voltage indicating a setpoint gain for the RF transmit signal path. In the closed-loop ALC mode, the analog control signal corresponds to an ALC reference voltage indicating a setpoint power output level for the RF transmit signal path.

  • Patent number: 10205512
    Abstract: Methods and apparatuses for enhancing flatness of frequency response of couplings of radio frequency (RF) ports in an RF switch matrix. Techniques include determining a second RF port has been selected to be coupled to a first RF port via a coupling, obtaining an indication of a frequency or frequencies to be carried via the coupling, determining an amount of attenuation or amplification for the coupling for the frequency or frequencies, and adjusting attenuation or amplification applied to the coupling according to the determined amount attenuation or amplification.

  • Patent number: 9831940
    Abstract: A method including determining that a first radio frequency (RF) port has been selected to be coupled via an M by N RF switch matrix to a second RF port, wherein the M by N radio frequency (RF) switch matrix includes M first-side RF ports and N second-side RF ports, the first RF port is included in the M first-side RF ports, the second RF port is included in the N second-side RF ports, M is at least 2 and N is at least 2, and each of the first-side RF ports may be selectively coupled to and uncoupled from at least one of two or more of the second-side RF ports, such that RF signals are carried between selectively coupled RF ports; obtaining a first indicator indicating a frequency, frequency range, channel, or band for an RF signal to be carried via the second RF port while coupled to the first RF port; obtaining, in response to the determination that the first RF port has been selected to be coupled to the second RF port, a first adjustment value based on the first indicator, the first RF port, and the secon
