Description

RF Antenna Eval Board 80 MHz - 3 GHz

This RF antenna switching board provides selectable routing between three wideband antennas and a direct RF connection path. The supported antenna frequency ranges are 80–450 MHz, 400–900 MHz, and 800–3000 MHz, enabling broad RF coverage across VHF, UHF, and microwave bands.

A direct-connect RF path is also included for bypass or external signal routing applications. Antenna selection is controlled through three 3.3 V GPIO logic inputs, allowing easy integration with microcontrollers, FPGA systems, or embedded RF platforms. The board is designed for flexible antenna management in communication, SDR, and RF monitoring applications.
