General Description
A7700 is a high performance and low cost 2.4GHz RF front end by CMOS technology. It integrates PA (up to 19dBm output power), LNA (gain up to 11 dB), RF switch as well as matching network so that only a few external components are needed. A7700 consists of two stages PA to provide extended link budget (distance) of larger TX output power and LNA for higher RX sensitivity in a wireless system. A7700 also has a very low sleep current (1.0 uA) for not only portable consumer electronic device but wireless sensor applications (IEEE 802.15.4) in the 2.4 GHz ISM band. All features are integrated in a small QFN-16 3X3mm package. Overall, A7700 is a range extender for all existing AMICCOM’s 2.4GHz TRX to provide users the total solutions of 2.4GHz high power module design including PCB layout, matching network and performance optimization.
