1. A signal booster system comprising:
a first unit configured to receive a radio frequency (RF) downlink signal from a base station antenna and to provide a boosted RF uplink signal to the base station antenna for wireless transmission, wherein the first unit comprises a first booster circuit; and
a second unit configured to connect to the first unit by a cable, wherein the second unit is configured to receive an RF uplink signal from a mobile station antenna and to provide a boosted RF downlink signal to the mobile station antenna for wireless transmission, wherein the second unit comprises a second booster circuit configured to separate the RF uplink signal into a high frequency uplink signal and a low frequency uplink signal, wherein the second unit amplifies the high frequency uplink signal but does not amplify the low frequency uplink signal.
