Thermal management of radio-frequency filters in a wireless networking device

A method comprising:

• receiving, by a thermal management controller from a transceiver disposed in a wireless networking device, a signal indicating whether the transceiver is performing a data communication, wherein the wireless networking device further comprises a cooling device disposed in thermal contact with a radio-frequency (RF) filter coupled to the transceiver;
• in response to the signal indicating the transceiver is performing the data communication, operating, by the thermal management controller, the cooling device to actively cool the RF filter;
• and
• in response to the signal indicating the transceiver is not performing the data communication while the wireless networking device is powered on, operating, by the thermal management controller, the cooling device to stop actively cooling the RF filter.

A wireless networking device, comprising:

• a wireless communication circuit comprising a transceiver and a Bulk Acoustic Wave (BAW) filter coupled to the transceiver;
• and
• a cooling system coupled to the wireless communication circuit to cool the BAW filter, wherein the cooling system comprises:
• a Peltier cooler disposed in thermal contact with the BAW filter;
• and
• a thermal management controller coupled to the Peltier cooler and the transceiver, wherein the thermal management controller is configured to:
• receive a signal indicating whether the transceiver is performing a data communication;
• in response to the signal indicating the transceiver is performing the data communication, operate the Peltier cooler to actively cool the BAW filter;
• and
• in response to the signal indicating the transceiver is not performing the data communication while the wireless networking device is powered on, operate the Peltier cooler to stop actively cooling the BAW filter.
