IMPEDANCE MEASUREMENT SYSTEM AND MOBILE COMMUNICATION DEVICE COMPRISING AN IMPEDANCE MEASUREMENT SYSTEM

摘要

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.
