A wideband frequency conversion module operating at millimeter-wave (MMW) band is proposed in this brief. By up-converting the input intermediate frequency (IF) of 6 GHz with the local oscillator (LO) signal of 13~17 GHz, it can generate the output radio frequency (RF) signal of 32~40 GHz. Firstly, to distinguish the exact position of RF signal from unwanted signal, the detailed spectrum simulation is performed based on the MMW mixer model. After that, some in-band interference signals of 2LO, 3LO-IF and 2LO+2IF overlap with the output RF range are found. To address the issue, a wideband filter is added in LO path to reject LO and 3LO. And more importantly, a switchable waveguide filter integrated in the module is designed to divide the whole RF working band into three sub-bands, thus guaranteeing the output spectrum purity. Through the final measurement, the RF signal power of 6.9~8.5 dBm and the spurious rejection level of 55 dB is obtained. |
