Abstract:State-of-the-art duplexers for mobile phones show significant variations of insertion loss within the transmitter (TX) and receiver (RX) frequency bands. The result is a high in-band loss due to the high attenuation requirements. This paper presents a novel concept and experimental results about minimizing loss in the transmit path. Splitting the full transmit band into two half bands reduces the insertion loss significantly by using two optimized TX filters. Both TX paths are connected to the antenna by a low… Show more
