WiFi-FES (Frequency Converters)

The WiFi-FES is a unique RF front-end subsystem that provides bi-directional frequency shifting of Wi-Fi signals. It leverages the Doodle Labs Prism® technology to enable the use of state-of-the-art, spectrum efficient Wi-Fi technology in the proprietary bands. Due to it’s flexible architecture, the WiFi-FES can be used like Lego building blocks to develop a wide variety of new wireless modems. The WiFi-FES is developed to be used with the newer CPU boards that have built-in Wi-Fi radios. The WiFi-FES helps to increase the range of these integrated Wi-Fi radios by improving the Tx power and Rx sensitivity.
System Integration

As shown in the block diagram, the modular nature of the WiFi-FES allows a very simple system integration with CPU boards. Only the RF signal is required from the radio and WiFi-FES works as an in-line module to the antenna. The WiFi-FES can work with a wide input voltage range of 6-42V. The WiFi-FES are compact in size and provide mounting flexibility inside the modem casing.

Available Models
