A Doherty amplifier (100) for amplifying an input signal to an output signal, the Doherty amplifier (100) comprising: a main amplifier (110) for receiving a first signal and for amplifying the first signal to generate a first amplified signal; a first peak amplifier (112) for receiving a second signal and for generating a second amplified signal, the first peak amplifier (112) only operating when the second signal has reached a first threshold power, the first and second signal split from the input signal; and output circuitry (106) to combine the first and second amplified signals to generate an output signal having an operating bandwidth, the output circuitry (106) comprising inductors (124, 126) arranged in the format of a branch line coupler, the inductors (124, 126) coupled to the output parasitic capacitances of the main (110) and peak amplifier (112).
