This paper reports on the characteristics of n+-GaAs/δ(p+)-GaInP/n-GaAs camel-gate heterojunction field-effect transistor (CAMFET) with the triple-step doped-channel. Due to the newly designed structure, the measured gate-drain turn-on and breakdown voltages are as high as 1.6 and 40 V for a fabricated 1 × 100 μm2 device, respectively. Furthermore, the measured maximum transconductance is 145 mS/mm with the current gain cut-off frequency fτ of 17 GHz and the maximum oscillation frequency fmax of 33 GHz, respectively. Based on excellent device characteristics, the studied device shows a promise for circuit applications.
