What is SAW Duplexer : Top Manufacturers for RF Solutions

A SAW duplexer is a radio frequency component based on Surface Acoustic Wave technology that enables simultaneous transmission and reception of signals using a common antenna. It provides excellent frequency separation, low insertion loss, and compact integration for LTE, 5G, IoT and wireless communication devices.

SAW duplexers are vital in RF communication systems. The SAW device which separates two frequency bands which are close together is also known as a SAW duplexer. It uses narrow band filters in order to perform band separation.

SAW Duplexer Selection guide

Following are the technical specifications of SAW duplexers to be considered while buying one for your needs:

• Balanced type or Unbalanced type
• Pass Band frequency ranges
• Insertion Loss (dB)
• VSWR (dB)
• Absolute rejection (dB)
• Isolation between Tx to Rx (dB)
