Abstract :
A new on-chip miniaturized diplexer, implemented on glass-based integrated passive device (GIPD) process using dual-mode right- and left-handed synthesized coplanar waveguides (CPWs), is proposed and validated. The right-handed synthesized CPW is identical to a 50-Ω line in the low band but resembles an open circuit in the high band. The left-handed one, on the contrary, serves as an open circuit in the low band but becomes equivalent to a 50-Ω line in the high band. This unique property makes the proposed design require no extra matching section. The on-chip diplexer shows a very compact size of 0.0174 × 0.0171 λg2, along with low power dissipation (0.6-0.8 dB) and moderate operating bandwidth (11-19%) at 2.6/5.8 GHz.
