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.

Abstract
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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
