This work presents the first example of monolithically integrated phase shifter based on a pass-band filter architecture. The proposed configuration was realized mapping a classical quarter-wave coupled filter circuit into its lumped element equivalent. Phase control is achieved by controlling the pass-band through tunable tanks employing varactor diodes. A demonstrator was prototyped in the 24 GHz ISM band using a 0.25μm SiGe BiCMOS technology. Experimental results show 180° of phase range and maximum transmission losses of 8 dB. The main feature of this configuration is that it allows controlling the transmission losses by design and that its size is extremely compact.
