【Abstract】 This paper presents a design scheme of a Ku band based frequency conversion transceiver front-end frequency integrated component system. In the design scheme, the input signal frequency of the transmitting branch is 160MHz±7.5MHz, the output frequency is16GHz±1GHz, and the transmitting power is greater than +13dBm. The receiving branch input signal frequency is 16 GHZ ±1GHz and the output intermediate frequency signal frequency is160MHz±7.5MHz, and the stray rejection is greater than 50dBc. Finally, we develop a prototype to test each part of the circuit, the test results verify the effectiveness of the scheme.更多还原
