Abstract:An LTCC test panel including various mm-wave test circuits has been designed and manufactured using a recently developed screen printing process (Thales Microelectronics) having a highly optimised resolution; here evaluated using a minimum microstrip line width/ gap of 2 mil (50.8 µm). In this paper we report on a 60 GHz microstrip coupled lines bandpass filter manufactured on a 3.7 mil (94.0 µm) thick Ferro A6S substrate using a minimum line gap of 2 mil. The electromagnetic effects caused by the top conductor recess were taken into account using direct full-wave simulations (Ansoft HFSS) but also by a circuit simulation methodology based on the use of effective relative permittivity and substrate height parameters [1]. Preliminary measurement results show a 3 dB bandwidth of approximately 5 GHz; a passband insertion loss of 4 dB and a center frequency slightly above the simulated value. This bandpass filter could e.g. serve as an image rejection filter together with the 60 GHz WLAN chipset [2] where it would demonstrate a 55 GHz image suppression of approximately 20 dB
