Novel ultra-compact 868 MHz/5GHz lowpass–bandpass diplexer for IoT

In this paper, we present a novel lowpass–bandpass diplexer designed to operate at frequencies of 868 MHz and 5 GHz. This diplexer is designed to overcome the limitations identified in previous studies. Notably, it achieves a maximum group delay of – 0.77 ns in the second passban...
