“…Due to the significant impact of dissipative networks on insertion loss, resistors are not suitable use in the design of compensation circuits. According to the conversion relationship between impedance and transmission matrix, 15 the transmission matrix A 0 B 0 C 0 D 0 of the compensation network can be constrained by (2).…”

“…The new generation WiFi7 RF transceiver system has put forward higher demands for bandwidth, requiring backward compatibility and coexistence with legacy bandwidth, 1 making research on wide-band RF switches essential. [2][3][4][5][6][7] In most RF switch applications and designs, obtaining a wider bandwidth while ensuring low insertion loss is a great challenge. For broadband applications, switches using a π-type topology consisting of a transmission line and two parallel capacitors or using an additional inverting spiral coupled line have been proposed.…”

SummaryAn off‐chip compensation technology for low‐loss and broadband characteristics of radio frequency (RF) switches is proposed based on mathematical analysis of series shunt single pole double throws switches in this letter. This compensation technology can absorb the parasitic parameters of the switch Field Effect Transistor, improving the insertion loss and return loss of the switch as well as supporting higher bandwidth. To verify the design principle, a RF switch, using the SANAN GaAs 0.15 um pseudomorphic High Electron Mobility Transistors (pHEMT) process, and an off‐chip compensation network were designed and implemented. Specifically, after using an off‐chip compensation network, the measured bandwidth of switch has been expanded from 1.1–8.8 to 0.8–11 GHz, while the input and output return loss have also improved significantly.

“…Past studies have shown that switches based on GaAs/GaN are less integrated and more expensive 2,3 . SiGe-based switches have the disadvantage of large insertion loss 4,5 . So, new technologies are desired to fabricate high-quality RF switches with the advantages of low insertion loss, high isolation, wide bandwidth, and a high power handling capability.…”

To realize a better radio frequency (RF) communication system, the RF switch, as an important module, is used to cooperate with other devices to form an RF front end for optimizing communication performances. This paper designs a single-pole multi-throw (SPMT) RF switch, which exhibits a low insertion loss of 0.57 dB at 1.9 GHz under the voltage of 2.2 to 4.7 V. The RF switch is fabricated using a 130 nm silicon-on-insulator (SOI) complementary metal-oxide-semiconductor (CMOS) process. It can be used in multi-frequency and multi-mode applications such as 4G/5G. The proposed RF switch has competitive performance and can be combined with other modules to achieve better wireless communication and promote the development of ultra-wideband and multi-mode wireless communication systems.
