A7700=PA+LNA+Swicth _inductor
1. Typical Application 2400 ~ 2483.5MHz ISM Band System■Wireless Audio/Video SystemIEEE 802.15.4 and Zigbee System■Industry control Wireless metering and building automation■2.4GHz Helicopter and airplane radiocontroller
2. General DescriptionA7700 is a high performance and low cost 2.4GHz RF front end by CMOStechnology. It integrates PA (up to 19dBm outputpower), LNA (gain up to 11 dB), RF switch as well as matching network so that onlya few external components are needed.A7700 consists of two stages PA to provide extended link budget (distance) of largerTX output power and LNA for higherRX sensitivity in a wireless system. A7700 also has a very low sleep current (0.2 uA)for not only portable consumerelectronic device but wireless sensor applications(IEEE 802.15.4) in the 2.4 GHz ISM band. All features are integrated in asmall QFN-16 3X3mm package. Overall, A7700 is a range extender for all existingAMICCOM’s 2.4GHz TRX to provideusers the total solutions of 2.4GHz high power module design including PCB layout,matching network and performanceoptimization.
