Tunnel injection transit-time diodes (TUNNETT) were fabricated with molecular layer epitaxy (MLE) and a 390 × 440 μm patch antenna was coupled with the GaAs TUNNETT diode for cavity-less sub-terahertz (THz) oscillators. The obtained sub-terahertz continuous wave (CW) was 177-197 GHz with a detected power of -35.3 dBm at 197 GHz under a bias current of 550 mA.
