Multiplexer – Diplexer
This RF Diplexer utilizes two ports that allows two different types of filters into one package. The most common topology we use, typically involves a High Pass and Lowpass combination. This combination can be altered based on customer specifications.
Similar to any product that can be tailored or made to order Bree Engineering’s Diplexers can be adjusted to meet any specification, and we are happy to provide simulations based on different requirements. This particular Diplexer provides a lowpass passband between 1425 and 2200 MHz with low Insertion Loss and consistent Return Loss. The lowpass also contains a solid 50 dB of isolation from the high pass and carries out this isolation through 14 GHz. The High pass maintains low loss through the passband of 2850 to 14000 MHz while keeping a consistent VSWR through the same passband. The opposing isolation from the lowpass is also held to 50 dB.
As with all of our Filters here at Bree Engineering the design is custom and tailored to the specifications of our clients. We are always striving to do our best to design, build and tune filters of any type.
Please see the attached Filter Test Data for the performance of the filter.
