RF Control Products

RF control products are fundamental electronic components that direct or modify radio frequency signals. For example, RF switches direct the RF signal to one of several possible paths while RF attenuators reduce the signal strength for purposes such as feedback control. Richardson RFPD has a broad offering of RF control products from leading manufacturers.
