A radio frequency (RF) module is a single unit that integrates two or more discrete components such as RF switches, low noise amplifiers, filters, duplexers, and power amplifiers, thereby enhancing integration and performance while achieving miniaturization. Depending on the integration method, RF modules can be categorized into different types with varying functions. Our company's RF module products include DiFEM (Diversity Receiver Module, integrating RF switches and filters), LFEM (Diversity Receiver Module, integrating RF switches, low noise amplifiers, and filters), LNA BANK (Diversity Receiver Module, integrating multiple RF low noise amplifier and RF switch functions), and WiFi FEM (WiFi Connection Module, integrating various combinations of WiFi RF power amplifier, RF switch, and low noise amplifier). These RF module products are primarily used in mobile intelligent terminals and network communication devices.
