- Abstract
- In this paper, a v-band MMIC self oscillating mixer active integrated antenna using a push-pull patch antenna is presented. The SOM AIA is based on the coupled active parallel feedback oscillator. By using a push-pull patch antenna, the isolation between balanced RF input and in-phase local oscillation is established. Furthermore, since the push-pull patch antenna has very low radiation efficiency for the in phase signal injection, the LO radiation was efficiently suppressed. The circuit is fabricated using the 0.15 mu m pHEMT process on 100 mu m thick GaAs substrate. The local oscillation frequency is 58.46GHz. The LO radiation level is measured to be lower than -50dBm at distance of 1cm. The circuit shows about -18.9dB effective isotropic conversion gain at 1.54GHz IF.
