The invention proposes a device for providing tunable high-frequency and/or radio-frequency
comprising within one IC-package at least four signal paths providing at least
two input and at least two output ports (rf-port1, rf-port2, rf-prot3,
rf-port4) at least one active component (T) and at least one variable passive
component (C1, C2) connected at least with an input port
of the active component (T), and at least one control path for controllable tuning
the at least one variable passive component (C1, C2).
