Transceiver assembly protection element

An electronic communications device, comprising:

• a housing;
• and
• a transceiver assembly configured to enable wireless communications with other electronic devices, the transceiver assembly comprising:
• a radio frequency (RF) transceiver configured to transmit and receive RF signals;
• a transceiver controller operatively coupled with the transceiver via a transmit path and a receive path;
• a power amplifier disposed along the transmit path between the transceiver controller and the transceiver, the power amplifier configured to amplify RF signals received from the transceiver controller for transmission by the transceiver;
• a power detection line configured to provide power control feedback to the transceiver controller indicating an amplitude of current flowing from the power amplifier to the transceiver;
• and
• a directionally-specific protection element disposed along the power detection line, the directionally-specific protection element configured to allow the power control feedback to flow to the transceiver controller over the power detection line in a first direction, while preventing at least some electrical noise originating from the transceiver controller from flowing through the power detection line in a second direction, thereby preventing the electrical noise from entering the receive path.

A transceiver assembly, including:

• a radio frequency (RF) transceiver configured to transmit and receive RF signals;
• a transceiver controller operatively coupled with the transceiver via a transmit path and a receive path;
• a power amplifier disposed along the transmit path between the transceiver controller and the transceiver, the power amplifier configured to amplify RF signals received from the transceiver controller for transmission by the transceiver;
• a low-noise amplifier disposed along the receive path between the transceiver and the transceiver controller, the low-noise amplifier configured to amplify RF signals received from the transceiver for processing by the transceiver controller;
• a power detection line configured to provide power control feedback to the transceiver controller indicating an amplitude of current flowing from the power amplifier to the transceiver;
• and
• a directionally-specific protection element disposed along the power detection line, the directionally-specific protection element configured to allow the power control feedback to flow to the transceiver controller during transmission of RF signals by the transceiver, and configured to redirect electrical noise originating from the transceiver controller away from the receive path and toward ground during receiving of RF signals by the transceiver.
