Circuits and methods for reducing insertion loss effects associated with radio-frequency power couplers

A radio-frequency (RF) device comprising:

• a transceiver configured to process RF signals;
• an antenna in communication with the transceiver, the antenna configured to facilitate transmission of an amplified RF signal;
• and
• a power amplifier (PA) module connected to the transceiver, the PA module configured to generate the amplified RF signal, the PA module including a first path configured to route a first RF signal in a first band, the PA module further including a second path configured to route a second RF signal in a second band, the PA module further including a power detector having a first coupler configured to detect power along the first path and a second coupler configured to detect power along the second path, the first coupler and the second coupler connected in a daisy-chain configuration, the PA module further including an adjustment circuit implemented along at least one of the first path and the second path, the adjustment circuit configured to move a frequency response feature associated with the power detector to a different frequency range.
