Abstract :
A power MMIC operating with a single-supply (3.0 V) has been developed for 5.8 GHz Japanese electronic toll collection system (ETC). The present MMIC was provided with two FETs, matching circuits (input, intermediate and output matching circuits), and two drain bias circuits. High dielectric constant material SrTiO/sub 3/ (STO) is used for by-pass and coupling capacitors. Very small die size of 0.77 mm/sup 2/ has been realized by using the STO capacitors. High 1 dB output power compression point (P/sub 1dB/) of 13 dBm, high gain of 21.4 dB and low dissipation current of 41.3 mA have been achieved under 3.0 V single-supply condition.
