Description
HopeRFs RFM22B/23B are highly integrated, low cost,433/868/915MHZ wireless ISM transceivers module. The low receive sensitivity(–121dBm) coupled with industry leading +20dBm output power ensures extended range and improved link performance. Built-in antenna diversity and support for frequency hopping can be used to further extend range and enhance performance.
