    Abstract: A detector circuit for determining an unknown load impedance (Zx) without the need for a signal level detector is provided. The detector circuit comprises a phase detector to derive two phase differences (α, β) between three input signals (V12, V10, V20) and a calculation circuit to derive a signal ratio.

    Abstract: An impedance measurement system (IMS) is provided that comprises an RSSI chain (RSSI), a limiter RSSI chain (LIMRSSI) and a limiter chain (LIM). The RSSI chain and the limiter RSSI chain are connected to a subtraction circuit (SC) and the limiter RSSI chain and the limiter chain are connected to a phase detector (PD). Further, a mobile communication device is provided that comprises the impedance measurement system in an adaptive impedance control system.
