Apparatus, and an associated method, facilitates maintenance of ambient temperature levels within a radio base station cabinet above a minimum temperature level. During periods of low activity at a radio base station, signals are applied to a power amplifier of the transmitter portion of the radio base station. Thermal energy is generated as a byproduct of amplification of the signals provided thereto. The signals are selected such that the signals are rejected by filter circuitry, such as the duplexer filter circuitry, of the radio base station. Thereby, thermal energy is generated but amplified signals are prevented from being transmitted by the radio base station. |
