RADIO FREQUENCY COUPLER CIRCUITRY

摘要

RF coupling circuitry includes a first coupled signal output node, a second coupled signal output node, an RF coupler, RF filtering circuitry, and attenuator circuitry. The RF coupler is configured to couple RF signals from an RF transmission line to provide coupled RF signals. The RF filtering circuitry is coupled to the RF coupler and configured to separate RF signals within a first RF frequency band in the coupled RF signals from RF signals within a second RF frequency band in the coupled RF signals. The attenuator circuitry is coupled between the RF filtering circuitry, the first coupled signal output node, and the second coupled signal output node. The attenuator circuitry is configured to attenuate the RF signals within the first RF frequency band and the RF signals within the second RF frequency band.
