RF Diplexers are often used in wireless communications, broadcast and satellite TV, radio and other fields. The SD25-0897R9UBQ1 Diplexer is a specific type of RF Diplexer, which typically applies to aggregate band applications with pass-bands of 0-2.7 GHz and TX/RX Bandwidths of 0-1.875 GHz and 1.55-2.7 GHz respectively.

In general, a Diplexer consists of two high-pass filters and two low-pass filters, each designed to pass frequencies on either side of the nominal cut-off frequency in each direction. Combining these elements into a single board assembly allows two different signals to share a single transmission line. This helps to reduce cost, board area and PCB material consumption.

SD25-0897R9UBQ1 Application Field

The SD25-0897R9UBQ1 Diplexer offers excellent performance and a broad range of uses. It is suitable for a variety of applications, including aggregate band partitioning, wideband multiplexing, WLAN and WiMAX communication, satellite communication and digital broadcasting. It can also be used for 5G digitized microwave communication, 5G terminal communication and signal distribution in complex networks.

SD25-0897R9UBQ1 Working Principle

The SD25-0897R9UBQ1 Diplexer consists of two ceramic monoblock condensers as a main body, which are connected in series to form a low-pass filter with a passband of 0-2.7 GHz. The low-pass filter passes the low-frequency signal, while the two high-pass filters, composed of inductors and monoblock condensers, are used for high-frequency signal transmission. The high-pass filters are designed to pass the frequency range of 1.55-2.7 GHz and 0-1.875 GHz, providing Tx and Rx signals respectively. The two high-pass and low-pass filters are integrated onto a single PCB, which allows two different signal paths to be transmitted simultaneously on one transmission line.

The SD25-0897R9UBQ1 Diplexer complies with the relevant Rohde & Schwarz RF requirements and is designed to meet the stringent accuracy and linearity standards demanded by the radio industry. It is certified by CE, RoHS and REACH, and is manufactured to ISO-9001 quality standards. Its excellent performance and reliability make it ideal for a wide variety of industrial and consumer applications.

In conclusion, the SD25-0897R9UBQ1 Diplexer is an excellent choice for aggregated band applications. It is well suited for applications such as WLAN and WiMAX communication, 5G digitized microwave communication, satellite communication and digital broadcasting. It is robust and reliable, certified by CE, RoHS and REACH and designed to meet the stringent accuracy and linearity standards demanded by the radio industry.
