SIGNAL PROCESSING DEVICE FOR DISTRIBUTED ANTENNA SYSTEM

摘要

A signal processing device according to an exemplary embodiment of the inventive concept can integrate a power amplifier, a duplexer, and a linearizer as a module to improve the convenience of management and to improve flexibility and extensibility so as to be transformable corresponding to a change in system development concept.

主权项

1. A signal processing device comprising:
a base module including a power amplifier; a first module coupled to the base module and selectively including an RF processing unit for processing an RF signal; a circuit substrate detachably coupled to the first module and including a linearizer correcting a distortion signal; and a second module covering the first module and including a duplexer separating a transmitted or received RF signal.
