Disclosed are circuits and methods for reducing insertion loss effects associated with radio-frequency (RF) power couplers. In some implementations, an RF circuit can include a first path configured to route a first RF signal in a first band, and a second path configured to route a second RF signal in a second band. The RF circuit can further include 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 can be connected in a daisy-chain configuration. The RF circuit can further include an adjustment circuit implemented along at least one of the first path and the second path. The adjustment circuit can be configured to move a frequency response feature associated with the power detector to a different frequency range.
