APPARATUS AND METHODS FOR RADIO FREQUENCY SIGNAL BOOSTERS
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.
1 . A radio frequency signal booster comprising:
a housing;
a first printed circuit board (PCB) positioned within a first cavity of the housing, wherein the first PCB includes a first plurality of amplification paths configured to boost a first plurality of radio frequency bands, wherein the first plurality of radio frequency bands each have a frequency less than about 1 GHz;
a second PCB positioned within a second cavity of the housing, wherein the second PCB includes a second plurality of amplification paths configured to boost a second plurality of radio frequency bands, wherein the second plurality of radio frequency bands each have a frequency greater than about 1 GHz; and
a shielding structure positioned between the first PCB and the second PCB.
