Abstract: A pseudomorphic high electron mobility transistor (PHEMT) includes a channel layer; a lower barrier layer and an upper barrier layer that are respectively disposed on two sides of the channel layer, where the lower barrier layer is connected to the channel layer; and a first isolation layer and a first doped layer that are disposed between the channel layer and the upper barrier layer, where the first isolation layer is configured to isolate the first doped layer from the channel layer, and the first doped layer is configured to provide two-dimensional electron gas. When an output current of the PHEMT is less than a first threshold, a conduction band energy level of the channel layer is less than a Fermi energy level. This improves linearity of the PHEMT under a small output current, and reduces intermodulation distortion caused by low noise amplifier (LNA) nonlinearity.
