本頁比較了雙工器、四工器、六工器和五工器，並提到了雙工器、四工器、六工器和五工器之間的區別。

This page compares Duplexer vs Quadplexer vs Hexaplexer vs Pentaplexer and mentions difference between Duplexer, Quadplexer, Hexaplexer and Pentaplexer.

Let us understand functions of these devices and their construction.

 Duplexer

如圖所示，該設備將有兩個端口（Tx、Rx）和一個天線端口。雙工器用作 2 端口到 1 端口多路復用器/解復用器設備。它用於復用/解復用 GSM、CDMA 和 LTE 系統中的發射和接收頻段。所示的 SAW 濾波器可用作 SAW 雙工器設備。

The device will have two ports (Tx, Rx) and one antenna port as shown. Duplexer functions as 2 port to 1 port multiplexer/de-multiplexer device. It is used to multiplex/de-multiplex transmit and receive bands in GSM, CDMA and LTE systems. SAW filters shown can be used as SAW duplexer device.

Quadplexer

如圖所示，除 1 個天線端口外，還有 4 個端口。 Quadplexer 用作 4 端口到 1 端口多路復用器/解復用器設備。該圖描繪了具有 2 個接收端口（P3 和 P5）、2 個發送端口（P2 和 P4）和一個天線端口（P1）的四工器設備。由於其超小的尺寸要求，它可用於降低整體終端設備開發的成本。此外，它是空間受限應用的理想選擇。

As shown there are 4 ports other than 1 antenna port. Quadplexer functions as 4 port to 1 port multiplexer/de-multiplexer device.The figure depicts quadplexer device with 2 receive ports (P3 and P5), 2 transmit ports (P2 and P4) and one antenna port (P1). Due to its ultra less size requirements it can be used to reduce cost of overall end device development. Moreover it is ideal for space constraint applications.

Hexaplexer

如圖所示，除 1 個天線端口外，還有 6 個端口。 Hexaplexer 用作 6 端口到 1 端口多路復用器/解復用器設備。在 6 個端口中，3 個端口用作接收端口，其餘 3 個端口用作發送端口。

As shown there are 6 ports other than 1 antenna port. Hexaplexer functions as 6 port to 1 port multiplexer/de-multiplexer device. Out of 6 ports, 3 ports are used as receive ports where as the rest of the three ports are used as transmit ports.

Pentaplexer

如圖所示，除 1 個天線端口外，還有 5 個端口。 Pentaplexer 用作 5 端口到 1 端口多路復用器/解復用器設備。在 5 個端口中，2 個端口用作接收端口，其餘三個端口用作發送端口。

As shown there are 5 ports other than 1 antenna port. Pentaplexer functions as 5 port to 1 port multiplexer/de-multiplexer device. Out of 5 ports, 2 ports are used as receive ports where as the rest of the three ports are used as transmit ports.
