What is fbrx?

As for power control, Qualcomm makes use of FBRX (Feedback Receiver) method: As shown above, the output power is usually coupled back to transceiver by means of the coupler integrated in ASM (Antenna Switch Module). In wireless transceivers, direct conversion can be used for the transmitter (TX) and/or receiver (RX). A base-band to radio-frequency feedback receiver (BB-RF-FBRX) architecture is proposed in this paper, which reflects the base-band selectivity to the RF input. asymmetric bandwidth requirement between RX and TX and FBRX may give multiple options to a system engineer depending on the following design. 4A is a block diagram of an example transceiver front-end with antenna diversity and a feedback receive (FBRx) path, in accordance with certain aspects of the.
