Abstract: A signal processing device includes a signal input, a signal output, a first amplifier, a second amplifier, a first distortion adjustment circuit, and a second distortion adjustment circuit. The signal input receives a RF signal to be amplified. The signal output outputs an amplified RF signal. Each of the first and second amplifiers includes an input coupled to the signal input and an output coupled to the signal output. The first distortion adjustment circuit includes a connection coupled to the input of the first amplifier. The second distortion adjustment circuit includes a connection coupled to the input of the second amplifier. The number of transistors in the first amplifier is different from the number of transistors in the second amplifier.
