Abstract
Disclosed herein are configurations and devices for amplifying radio-frequency signals. The devices and configurations include using a wide-band or tunable downstream amplifier to amplify signals in a downstream or back-end module. The signals are first filtered and amplified by an upstream or front-end module that receives a diversity signal from a diversity antenna.

A diversity receiver configuration comprising:
- a diversity receiver (DRx) module configured to receive a diversity signal;
- a first DRx multiplexer configured to direct the diversity signal along at least one of a plurality of DRx paths;
- a plurality of pre-amplifier bandpass filters, individual pre-amplifier bandpass filters disposed along a corresponding one of the plurality of DRx paths;
- a plurality of DRx amplifiers, individual DRx amplifiers disposed along a corresponding one of the plurality of DRx paths;
- a plurality of post-amplifier bandpass filters, individual post-amplifier bandpass filters disposed along a corresponding one of the plurality of DRx paths;
- and a second DRx multiplexer configured to receive amplified and filtered signals from the plurality of post-amplifier bandpass filters and to provide an output DRx signal;
- a diversity radio frequency (DRF) module configured to receive the output DRx signal;
- a downstream amplifier configured to amplify the output DRx signal;
- and a downstream multiplexer configured to receive the amplified output DRx signal and to output a plurality of DRF signals for transmission to a transceiver;
- and
- a controller configured to communicate with the DRx module and with the DRF module, the controller configured to control an amount of gain provided by the downstream amplifier and the plurality of DRX amplifiers.
