Patent number: 10848187Abstract: Disclosed herein are wireless transceivers with switches to reduce harmonic leakage. The devices are configured to transmit and receive signals in a first frequency band and a second frequency band. The devices selectively decouple a power amplifier from a duplexer to reduce harmonic leakage into a receiving system. The decoupling is accomplished using a switch, the switch being operated responsive to a band select signal indicating the second frequency band as a receive band but not a transmission band and the first frequency band as a transmission band where the first frequency band has at least one harmonic that lies within a downlink sub-band of the second frequency band.Type: GrantFiled: May 7, 2019Date of Patent: November 24, 2020Assignee: SKYWORKS SOLUTIONS, INC.Inventors: Philip H.

Publication number: 20200067406Abstract: Described herein are systems, architectures, circuits, devices, and methods for a DC-DC converter that dynamically adjusts a supply voltage to a power amplifier based on the number of resource blocks in a signal to be transmitted. The disclosed technologies estimate the number of resource blocks in a signal, generate a signal corresponding to the estimated number of resource blocks, and modify a supply voltage based on the generated signal. These technologies can be used to increase the efficiency of power amplifier systems for cellular signals being transmitted that have fewer resource blocks than is typically assumed (e.g., at least 100 resource blocks).Type: ApplicationFiled: September 3, 2019Publication date: February 27, 2020Inventors: Sabah Khesbak, Florinel G.
