1. DESCRIPTION: 

The RXB2 is a ASK/OOK compatible super heterodyne receiver module.. RXB2 is a superior performance receiver for ISM band.  With the adoption of Infineon's Industrial RF wireless data receiver chip, RXB2 has the high receiving sensitivity and strong anti-interference ability.  It can do wireless signal input to the data signal output without any external circuit.  Its superior performance makes a lot of before market car manufactures adopt this module as the preferred choice for RKE receiver module. 

Users only need to decode the data plus a simple circuit and then any wireless products development can be easily achieved.
