AP6684
Quad-Band GPRS Front-End Module with Four UMTS Ports 

 
Product Overview
AP6684 is a quad-band GSM/GPRS ( GSM850 / GSM900 / DCS1800 / PCS1900 )   frond-end module (FEM) with four high linearity/ low insertion loss TRX ports for multimode applications.
This front-end module integrates high power/high efficiency PA blocks, high linearity/low insertion loss antenna switch and controller in a compact module. In addition, the built-in low pass filter rejects higher order harmonics and eliminates the need of external low pass filter network.
 
The AP6693 provides 50Ω matched input and output ports requiring no external matching network. It also integrates an ESD protection circuit to provide robust ESD protection at the antenna port.
