The design, simulation, modeling and characterization of low-temperature co-fired ceramics (LTCC) RF switch module for GSM band applications were investigated. RF switch circuits were simulated by ADS tool, manufactured using a LTCC multi-layer in the GSM band. It was integrated with low pass filter on switch module. Insertion and return losses at 900 MHz of the low pass filters were designed to lower than 0.3 db and higher than 12.7 db respectively. The RF switch module was constructed, containing 10 embedded passives and 3 surface mounted components integrated on 4.6×4.8×1.2 mm3 volume, 6-layer integrated circuit. The insertion loss of switch module at 900 MHz was about 11~19 db.
