Selection Guide
General Description
A7701 is a TX technology. It integrates PA (up to 23dBm output power), LNA (gain up to 16 dB), RF switch as well as matching network so that only a few external components are needed. A7701 consists of 3 stages PA to provide extended link budget (distance) of larger TX output power and LNA for higher RX sensitivity in a wireless system.
 Small size (QFN 3X3, 16 pins).
