The ADF7020 supports the 433MHz, 868MHz, and 915MHz Industrial, Scientific, Medical (ISM) frequency bands, along with their modulation schemes. With sensitivity reaching -117.5dBm, the ADF7020 can operate over an extended RF Range. Over 3km, or nearly 2 miles, range was achieved using 2 x ADF7020’s. The ADF7020 also features an excellent IP3 specification, or 3rd Order Intercept Point, which maintains good RF performance in noisy environments. Additional cost saving features include, Automatic Frequency Control (AFC), which allows the use lower cost crystals, and an integrated transmit/receive switch which eliminates the need for an external switch.
