Compact, robust and low profile ‘branchline’ devices are of thick film on alumina construction and are available in microstrip or surface mount technology (SMT) architectures. These products are offered for engineers and system designers who need exactitude and repeatability in performance with a true and consistent low insertion loss component, rather than settle for the uncertainties associated with a commodity type or LTCC device.
In addition, the alumina construction coupled with very high conductivity metal alloys provide for much higher input powers than other constructions such as PTE.
IMS has developed the 3 dB hybrids with center frequencies at 6.0, 6.5, 3.5, 4.0, and 4.6 GHz. Contact us with your specific requirements or to obtain a sample of our existing product. Size and insertion loss are generally determined by center frequency.
