This paper given a brief and concise discussion on latest research of RFIC power amplifier (PA) designs, showing the frontier state-of-the-art developments, and then present our PA designs and some typical newest designs in expertise area with three technologies, a.k.a CMOS, SiGe, and III-V semiconductor. At last, three research hotspots and research trends about on chip PA are summarized and discussed.
In this paper, a novel compact single-pole-double-throw (SPDT) switchable bandpass filter (BPF) realized on substrate integrated suspended line technology (SISL) is presented. A new hybrid resonator is proposed and analyzed, based on which the circuit size has been greatly reduced compared with the conventional one. Controlled by commercial PIN diodes, the on path of the proposed SPDT switch is designed...
