This mixer module achieves up and down conversion function within the frequency range of 5-21GHz, with a maximum frequency of up to 21GHz. This module adopts a CNC structure shell, which has good electromagnetic shielding performance. The module uses a high-frequency low insertion loss circuit board, with LO/RF operating in the broadband range of 5-21GHz and IF covering DC-5000MHz. It is applied to typical frequencies such as 5.8G, 8G, 12G, and 18G, achieving up and down conversion function. Widely used in corresponding frequency band transceiver systems, its small structure is easy to install and use.
