/Radio Frequency Signal Splitting With Differential Filter And Low Noise Amplifiers
Abstract

Apparatus and methods for radio frequency (RF) signal splitting are disclosed. In certain embodiments, a front-end system includes a filter that filters an RF receive signal to generate a differential filtered RF signal between a first output and a second output, a first low noise amplifier (LNA) that generates a first amplified RF signal by amplifying a first component of the differential filtered RF signal received from the first output, a second LNA that generates a second amplified RF signal by amplifying a second component of the differential filtered RF signal received from the second output, a first multi-throw switch that receives the first amplified RF signal, and a second multi-throw switch that receives the second amplified RF signal.
