300-GHz-Band InP HBT Power Amplifier and InP-CMOS Hybrid Phased-Array Transmitter
In this invited paper, we introduce a 300-GHz-band power amplifier (PA) IC and module designed and fabricated in 250-nm InP DHBT technology and a 300-GHz-band InP-CMOS hybrid phased array transmitter for 6G. Our PA module achieved a maximum gain of 30 dB around 260 GHz and maintained over 20 dB within a range from 220 to 310 GHz. It also achieved a saturation power of $9 \mathbf{~ d B m}$ at 270 GHz and demonstrated point-to-point wireless data transmission with a data rate of 100 Gbps at a distance of 40 m. Our phased array transmitter, in which four InP-HBT PA ICs and CMOS ICs containing mixers and control functions are integrated onto the same printed circuit board, achieved a maximum EIRP of $\mathbf{8. 4 ~ d B m}$ and steering range of 36° and successfully demonstrated wireless data transmission of up to 30 Gbps over a distance of 50 cm with beam steering.
