ABSTRACT:
A cordless telephone handset includes a burst mode transmitter/receiver unit comprising a radio (10) and a current sink (20) shunted across the radio. A controller (18) controls the current sink (20) in a feedback manner such that the sum of the currents drawn by the radio and the current sink is substantially constant, in order to compensate for fluctuations in the current drawn by the radio alone, so as to avoid interference at the burst rate when the handset is used in conjunction with a hearing aid.
