DISTRIBUTED DUPLEXER CONFIGURATION FOR BLOCKING AND LINEARITY

摘要

A telecommunications system may be configured to impove linearity and blocking. In some aspects, the telecommunications system may include a duplexer for coupling a common port to a receive path and a transmit path. A distributed low-noise amplifier having two or more separate active devices (e.g., amplifiers) may be positioned in the receive path. A filtering element (e.g., a band-pass filter) may be positioned between the two or more separate active devices. A signal may be routed by the duplexer through the distributed low-noise amplifier. The filtering element may attenuate transmit signals in the receive path.

1. A remote unit, comprising.
a duplexer couplable between (i) a common port and (ii) a receive path and a transmit path, the common port couplable to an antenna for transmitting downlink signals and receiving uplink signals; and a band-pass filter between a first amplifier and a second amplifier, the first amplifier and the second amplifier forming a low-noise amplifier in the receive path.
