摘要：
A power amplification circuit having three modes of operation and a single switch is disclosed. Only one switch is used to control three different load impedance levels, one load impedance level for each mode of operation. The remaining “switching” results from selectively biasing each power amplification path by turning ON or OFF amplifiers. A series L-C and a switch are used to control the load impedance. Additional modes of operation may also be created without requiring any additional switch. Further, multiple modes of operation may be implemented using no switches.
