An RF diplexer is a type of composite filter used in communication systems for the purpose of separating or combining two signals of different frequencies. The DPX2012LL89R2455A is a specific type of diplexer that is suited to a variety of applications within the microwave and radio frequency (RF) spectrum. This article will discuss the application field of the DPX2012LL89R2455A as well as its working principle.

Application Field

The applicability of the DPX2012LL89R2455A lies in the frequency range of 2 – 18 GHz. It has seen use in wireless broadcasting systems, satellite communications, radar systems, -80dB harmonic suppression systems, and various other uses. The DPX2012LL89R2455A is also useful for frequency ranges that require high-performance due to its low insertion loss of 1.8dB, and its high isolation of 22dB. The diplexer itself is a 12.2mm x 6.2mm ceramic chip.

Working Principle

At its simplest, a diplexer works by combining two frequencies into one channel, and then separating them again. The DPX2012LL89R2455A operates on a similar principle, but with more complexity. The diplexer is based on a waveguide filter which consists of one transmission line and several slots/holes on the walls of the waveguide. This creates a structure that acts as two band-pass filters in one unit, allowing two different frequencies to co-exist in the same signal. The diplexer is capable of separating the two frequencies, or combining the two frequencies, by creating an impedence mismatch.

The DPX2012LL89R2455A offers low reflectance, and high harmonic suppression due to its design, which employs a plurality of slots/holes, allowing the unit to filter out noise thereby resulting in cleaner signal transmission. Furthermore, the DPX2012LL89R2455A is designed to work in a wide temperature range of -40°C to +85°C.

Conclusion

To conclude, the DPX2012LL89R2455A is a type of RF diplexer ideal for use in applications requiring high performance within the frequency range of 2 – 18 GHz. It offers low insertion loss, high isolation, and wide temperature range. It is based on a waveguide filter which consists of one transmission line and several slots/holes on the walls of the waveguide, thereby enabling the diplexer to achieve its classification as a composite filter.
