RF diplexers are devices designed to separate or combine signals coming from multiple frequency bands. They offer a cost-effective and space-saving solution for combining different frequency signals into one line or splitting signals from one line differently. The DPX165850DT-8040A3 is one type of RF diplexer. This article explores its application field and working principle.

Application Field

The DPX165850DT-8040A3 is a two-way RF diplexer that has a frequency range of 1710-2185 MHz and low insertion loss of less than 3.2 dB in the pass band. It is designed to work with applications such as satellite uplink and broadcast, point to point wireless, cellular, Wi-Fi and microwave radio. The diplexer can be used to separate and combine different satellite signals while avoiding interference from other signals.

Working Principle

The principle of operation of a two-way RF diplexer (such as the DPX165850DT-8040A3) is simple. There are two diplexer ports, each of which is tuned to a specific frequency. The diplexer is placed between two antennae or other RF inputs, with each port connected to one antenna. As the RF signals enter the diplexer, the diplexer filters out all frequencies which are not tuned to the ports and sends them to the corresponding antenna. In this way, the diplexer allows only frequencies within the pass-band to pass through, while the other frequencies are blocked. In addition, the diplexer also prevents signals received by one antenna from interfering with signals received by the other antenna, thus increasing the signal clarity.

The DPX165850DT-8040A3 diplexer also has a high harmonic suppression capability, offering greater signal clarity and ensuring that only signals within its frequency range are allowed through the diplexer. The diplexer also has a low insertion loss of less than 3.2 dB in the passband, which minimizes signal loss and ensures that the signal is as clean as possible. Furthermore, the diplexer has an IP65-rated housing, which makes it suitable for use in a variety of harsh environments.

In summary, the DPX165850DT-8040A3 is a two-way RF diplexer that is designed to work with applications such as satellite uplink and broadcast, point to point wireless, cellular, Wi-Fi and microwave radio. It has a frequency range of 1710-2185 MHz, low insertion loss of less than 3.2 dB in the passband, high harmonic suppression capability, and an IP65-rated housing. The working principle of the diplexer is simple; it filters out all frequencies which are not tuned to the ports, prevents signals received by one antenna from interfering with signals received by the other antenna, and has a low insertion loss. The diplexer is a cost-effective and space-saving solution for combining different frequency signals into one line or splitting signals from one line differently.
