Abstract

A compact band pass filter with wide stop-band in land gird array (LGA) package was proposed in this paper. The proposed filter was designed to operate at 5.15 GHz–5.85 GHz for 802.11ac applications and implemented in low-temperature co-fired ceramic (LTCC) substrate. The proposed schematic introduces transmission zeros at the lower band to reject the unwanted frequency and extended wide stop-band at upper side with 30 dB rejection level from 9.55 GHz– 18.45 GHz. The measured insertion loss is less than 1.0 dB at 5150–5850 MHz. The rejection level at lower side can be achieved 38 dB from measurement results. The measurement results and simulation are both shown and discussed.
