Claim 14:
15. The system of claim 14, wherein said system is a base transceiver station (BTS) system, said BTS system further comprising:
a combiner coupled to said antenna;
a plurality of duplexers, each coupled to said combiner, said plurality of duplexers including said first duplexer; and
a plurality of transceivers including said first transceiver, each of said plurality of transceivers comprising a transmitter portion and a receiver portion coupled to a corresponding one of said plurality of duplexers at one end and a base station controller (BSC) at the other end, wherein each of said plurality of transceivers is designed to transmit into said wireless medium information signals received from said BSC via the corresponding one of said plurality of duplexers, said combiner and said antenna, as well as to forward information signals received from said wireless medium via the corresponding one of said plurality of duplexers, said combiner and said antenna to said BSC;
wherein said power supply unit comprises:
a plurality of DC-DC converters coupled to receive said power from said power terminal and to generate respective supply voltages, said plurality of DC-DC converters including a first DC-DC converter to generate a first supply voltage, wherein said first supply voltage is used to power a relatively noise-insensitive block in said first transceiver, wherein said first linear voltage regulator is coupled to receive said first supply voltage converter to generate said first lower supply voltage; and
a plurality of linear voltage regulators coupled to receive a supply voltage from a corresponding one of said DC-DC converters and to generate a corresponding lower supply voltage, wherein said plurality of linear voltage regulators includes said first linear voltage regulator,
wherein supply voltages generated by one or more of said DC-DC converters is used to power relatively noise-insensitive blocks in said plurality of transceivers, and wherein supply voltages generated by one or more of said linear voltage regulators is used to power noise-sensitive blocks in said plurality of transceivers, and
wherein at least a second linear regulator in said plurality of linear voltage regulators is implemented similar to said first linear voltage regulator.
