Abstract
Provided herein are apparatus and methods for radio frequency (RF) signal boosters. In certain implementations, a multi-band signal booster is provided for boosting the uplink and downlink channels of at least a first frequency band and a second frequency band. In certain configurations, the downlink channels of the first and second channels are adjacent, and the signal booster includes a first amplification path for boosting the uplink channel of the first frequency band, a second amplification path for boosting the uplink channel of the second frequency band, and a third amplification path for boosting both downlink channels of the first and second frequency bands.

(canceled)
A radio frequency signal booster comprising:
- a first multiplexer;
- a second multiplexer;
- a Band XII uplink amplification circuit configured to receive a Band XII uplink signal from a first terminal of the second multiplexer, and to provide an amplified Band XII uplink signal to a first terminal of the first multiplexer;
- a Band XIII uplink amplification circuit configured to receive a Band XIII uplink signal from a second terminal of the second multiplexer and to provide an amplified Band XIII uplink signal to a second terminal of the first multiplexer;
- and
- a shared downlink amplification circuit configured to receive a combined downlink signal from a third terminal of the first multiplexer and to provide an amplified combined downlink signal to a third terminal of the second multiplexer, wherein the combined downlink signal includes a Band XII downlink signal and a Band XIII downlink signal,
- wherein the shared downlink amplification circuit comprises a plurality of components in a cascade, the plurality of components including at least one amplifier configured to simultaneously boost both the Band XII downlink signal and the Band XIII downlink signal, and at least one bandpass filter configured to pass both the Band XII downlink signal and the Band XIII downlink signal.
