Abstract
Architectures for a class of multi-band handsets are described. These architectures separate linearity requirements from isolation requirements and reduce the number of throws on switches requiring linearity through the use of distributed switching, filter structure placement between the switch functions, not sharing a power amplifier between frequency bands that have a Tx to Rx overlap, and simplifying the switching structure using filtering networks or multiple antennas.
