摘要：

The results on the design and the measurement of a 5.8 GHz GaAs transmitter MMIC for electronic toll collection (ETC) system on-board equipment are presented. The MMIC of single chip and single supply without any external element is assembled into a 16-pin SSOP package. A novel drain-controlling modulation circuit is invented as a modulator to provide linear modulation. The measured adjacent channel power (ACP) is lower than -47 dBc. The on/off ratio of modulation is above 40 dB at 5.8 GHz under a random data modulation of 1.024 Mbps with Manchester coding.
