Abstract :
An oscillator based on distributed amplifier realized by using CRLH (Composite Right-/Left-Handed) unit cells is designed and experimentally validated. The positive feedback consists of a transmission line which connects the input port and drain idle port of the amplifier. The remaining two ports of the distributed amplifier are the oscillator output ports. For this oscillator topology, the transistors give the same contribution to the output power. The measured powers at the two output ports are equal to 12.6 dBm and 10.4 dBm. The experimental frequency of oscillation is 2.77 GHz, the difference compared to the simulated value being less than 1%.
