Pentaplexer Filter Manufacturers for LTE & 5G Mobile Phones

This page describes Pentaplexer SAW/BAW filters used in LTE and 5G mobile phones. It lists vendors and manufacturers of Pentaplexer filters based on SAW/BAW filter designs.

What is a Pentaplexer Filter?

A Pentaplexer filter is a multiplexer/de-multiplexer device with 5 ports (other than the antenna port), effectively functioning as a 5-to-1 port device.

As shown in the image, there are five ports in addition to the antenna port. Typically, two ports are used as receive (RX) ports, while the remaining three ports are used as transmit (TX) ports. The pentaplexer combines multiple TX and RX filters into a compact module.

The figure depicts a Pentaplexer device with 3 transmit ports, 2 receive ports, and one antenna port.

The primary benefits of using Pentaplexer filters in carrier aggregation systems are their ultra-small size and low cost.

Technical Specifications for Pentaplexer Filter Selection

When selecting or buying a Pentaplexer filter, consider the following technical specifications:

• Bands or Frequency Range: The supported frequency bands are critical for compatibility with your application.
• Insertion Loss (in Transmit Direction): Lower insertion loss is generally better, as it minimizes signal attenuation during transmission.
• Compact Form Factor: Size is crucial for mobile devices, so a compact form factor is highly desirable.
• Power Handling Capacity at Input Ports: The filter should be able to handle the expected power levels without degradation.
• VSWR at Tx Port, ANT Port: Voltage Standing Wave Ratio (VSWR) should be low for efficient signal transfer.
• Attenuation at Different Frequency Ranges: Ensure sufficient attenuation of unwanted signals to prevent interference.
• Tx to Rx Isolation: High isolation between transmit and receive paths is important to avoid signal leakage.

Example: The Qorvo model QM26003 is used as a Pentaplexer filter or as a multiplexer in LTE/5G systems.
