Abstract :
A four-element linearised distributed amplifier operating between 0.8 and 2.2 GHz is presented. The parallel diode linearisation technique is applied to a distributed amplifier resulting in a 14 dB gain linearised amplifier. The addition of the lineariser, gave a reduction in gain of less than 1 dB with a 7-12 dB reduction in spectral regrowth for the first sidelobe.
