Methods and systems for a configurable front end are disclosed. Aspects of one method may include a transceiver on a single chip that may comprise a power amplifier (PA) and a low noise amplifier (LNA). The PA may amplify signals to be transmitted over a range of output transmit power. An upper limit for a power range may of substantially 12 dBm. The LNA may be tolerant to PA signals by, for example, being configured to follow signal voltages generated from an output of the power amplifier. For example, each input transistor of the LNA may be isolated from other transistors in the LNA. Accordingly, the input transistors may float since they may not be tied to a voltage level via other transistors. This may allow the input transistors to avoid damage. The transceiver may also be configured for differential RF input, differential RF output, single-ended RF input, and/or single-ended RF output. In some configurations, the transceiver may also support use of a power amplifier external to the transceiver to amplify RF signals communicated by the transceiver. |
