DPX162500DT-8128A1 RF/IF and RFID

The DPX162500DT-8128A1 is a RF diplexer that allows two signals on two separate frequency bands to be combined, transmitted or received on a common port. In the application field, it is used in various high power transmit / receive applications where multiple signals operating on different frequency bands need to be combined or divided into individual bands. To make this possible, the device utilizes an applicable working principle that can effectively split or combine high power signals on different frequency bands.

The working principle of the diplexer utilizes a combination of band-pass filters and balanced power dividers or combiners to separate the signals to respective bands. The filters essentially block the frequencies that are not in the required frequency band range, while the dividers/combiners ensure equal power division or combination in each band. Thus, the gain is maintained at the output, while the noise and other undesired signals are eliminated.

The filter part of the diplexer is connected between the common port on one side and the respective antenna ports on the other. The filter consists of two pass-bands, one for each frequency band. Depending on the application requirement, it could be either two pass-bands with an overlap region, or one pass-band with a separate band-stop to stop any unwanted signals. The dividers/combiners are connected to the filters and the common port to ensure required power gain or division.

In terms of performance, the DPX162500DT-8128A1 diplexer allows simultaneous transmission and reception of signals on different frequency bands. It provides excellent frequency band isolation, frequency stability, power handling capability and excellent VSWR. The device also provides low insertion loss and negligible temperature coefficient. Furthermore, it is constructed with superior quality components to ensure high reliability and long life.

Overall, the DPX162500DT-8128A1 RF diplexer is an ideal device for combining or splitting signals into two different frequency bands. Its versatility and performance make it suitable for a wide range of high power applications, offered with superior stability and reliability.
