The Low-IF method is a frequency conversion system which enables one to obtain a very low Intermediate Frequency (IF) signal by mixing the local (LO) signal with the radio frequency (RF) signal in one mixer. The active integrated antenna is proposed to reduce transmission loss by unifying the antenna with a self oscillator as a local oscillator. However, the output power from the single self oscillator is low, so the RF-IF conversion gain becomes low. In this paper, the Push-Push oscillator, using a self oscillator, is proposed to achieve high power output. First, a self oscillator of 2.44GHz was used for the local oscillator and the RF-IF conversion gain was +5.4dB. Then the Push-Push oscillator was used and a gain of +8.5dB was obtained. The gain was improved by 3.1dB by through the use of the Push-Push oscillator.
