  • Radio frequency amplifier structure
    Patent number: 6128479
    Abstract: A radio frequency (RF) circuit (300) includes two parallel sections (310, 312) that are designed to function collectively through the use of a signal splitter/switching circuit (200) and a signal combiner (314). To optimize the performance of the RF circuit (300), a switching arrangement (214, 216, 218, 220, 222, 224, 226, 228, and 230) that is part of the signal splitter/switching circuit (200) is used to separate and isolate the two parallel sections (310, 312) for tuning purposes. After each parallel section (310, 312) has been individually tuned, the two parallel sections (310, 312) are recombined for joint operation.
