Enhanced Duplexer Module (E-Duplexer)

Qualcomm's E-Duplexers feature an integrated acoustic-based filter with enhanced power handling (downlink) and isolation, compared to SAW/BAW based duplexers. With > 70 dB isolation (typ.) and > +30 dBm Pin (avg.), they are suitable for 3G/4G LTE/5G – FDD systems as post-power amplifier duplexers in small cells and repeaters.


Features & Benefits

• 8.1mm x 8.1mm SMD type package
• Internally matched to 50Ω
• Single transmit, receive, and antenna ports
• High integration enables ease of use
• Very high Isolation enables Carrier Aggregation and Multicarrier radios
• Common footprint enables OEM platform-based development (700-2700MHz)
• Shared PCB layout with traditional duplexer 2.5x2.0mm size SAW/BAW enables platform design flexibility
