<p>A time-division radio (200) is disclosed that can use a lower-power energy source than radios in the prior art. An illustrative embodiment of the present invention comprises a time-division transmitter (209) that has a transmit mode and an idle mode, a primary energy storage device (201) and a secondary energy storage device (205). The radio uses the secondary energy storage device as a kind of "power cache" in which to store power when it is in abundance and from which to draw power when it is scarce. When the transmitter (209) is in idle mode, the primary energy storage (201) device charges the secondary energy storage device (205) and powers the transmitter. But when the transmitter is briefly in transmit mode, and, therefore, requires more power than the primary energy storage device alone can supply, the secondary energy storage device discharges to supplement the power from the primary energy storage device and satisfy the transmitter's power requirements. <IMAGE></p> |
