Abstract

Wireless subscriber radios often use recharge- able batteries as the primary energy source. Such batteries are typically charged with an external charger that comprises all the hardware and software required to perform that function. In order to mini- mize the size of the charger and reduce cost while providing simple operation to the end user, there is a trend to include most of the charger components in the subscriber radio. This is commonly referred to as a built in charger. In some of the earlier imple- mentations of such mini-chargers, however, radio cost and RF performance was compromised. The invention provides a configuration for a built in charger that does not compromise transmitter per- formance and maintains all the desired charging features.
