Abstract :
A MMIC (Monolithic Microwave Integrated Circuit) distributed amplifier with bandwidth of 8-40GHz was successfully developed. We proposed a novel structure for the distributed amplifier, that is separating the amplifier into two sections and connecting the two sections by a capacitor. By this means, we can get higher gain than the traditional distributed amplifier. The amplifier was successfully designed and fabricated with 0.15¿m PHEMT technology and the chip area is 2.8mm*1mm. Measured results show that the gain is 11dB in the bandwidth of 8-40GHz, and the input and output return loss are more than 10dB in the whole band.
