Distributed duplexer configuration for blocking and linearity

A telecommunications system, comprising:

• a duplexer couplable between (i) a common port and (ii) a receive path and a transmit path, wherein the duplexer has relaxed isolation characteristics for transmitted downlink signals in the receive path, wherein the duplexer allows at least some transmitted downlink signals to traverse the receive path;
• a distributed low-noise amplifier having two or more separate active devices in the receive path;
• and
• at least one filtering element positioned between the two or more separate active devices, wherein the at least one filtering element includes a first band-pass filter and a second band-pass filter;
• wherein the two or more separate active devices includes a first amplifier positioned between the duplexer and the first band-pass filter and a second amplifier positioned between the first band-pass filter and the second band-pass filter;
• wherein the first band-pass filter and the second band-pass filter are configured to pass uplink signals in a frequency range of the receive path.

A method, comprising:

• receiving a signal at a common port coupled to a receive path and a transmit path by a duplexer, wherein the duplexer has relaxed isolation characteristics for transmitted downlink signals in the receive path, wherein the duplexer allows at least some transmitted downlink signals to traverse the receive path;
• routing the signal through a first amplifier and a second amplifier in the receive path, the first amplifier and the second amplifier together forming a low-noise amplifier;
• and
• attenuating a transmit signal in the receive path using a first band-pass filter positioned between the first amplifier and the second amplifier, wherein the first amplifier is positioned between the duplexer and the first band-pass filter in the receive path;
• and
• attenuating a transmit signal in the receive path using a second band-pass filter in the receive path, wherein the second amplifier is positioned between the first band-pass filter and a second band-pass filter in the receive path;
• wherein the first band-pass filter and the second band-pass filter are configured to pass uplink signals in a frequency range of the receive path.
