US 2026/0039448 A1 · ARCHITECTURE FOR DUAL CHANNEL AMPLIFIER ISOLATION

Abstract

Methods and systems for dual channel amplifier isolation. A transceiver system includes a first antenna configured to transmit and receive radio frequency (RF) signals from a base station (BS), a second antenna configured to transmit and receive RF signals from a user equipment (UE), a processor configured to control an operating mode of the transceiver system, a first transceiver configured for time division duplexing (TDD) operatively coupled to the processor and a second transceiver configured for frequency division duplexing (FDD) operatively coupled to the processor. The first transceiver includes a first TDD amplifier stage, and a first TDD switch. The second transceiver includes a first FDD amplifier stage, and a first FDD duplexer.
