The 4-port differential phase shift isolators is a combined waveguide device. When the microwave signal passes through the isolator, it can be transmitted with low loss in the forward direction and has high isolation in the reverse direction. It is composed of a 3dB combiner/divider, a parallel ferrite 90° non-reciprocal phase shifter, and a folded […]

To achieve complete coverage with a minimum s-band antenna gain of -7 dBi, a straightforward configuration utilizing dual circularly polarized microstrip patch antennas was employed. The configuration involved the implementation of a wide bandwidth, dual circularly polarized truncated corner microstrip antenna, which was complemented by two parasitic patches. To enhance the cross polarization bandwidth, diagonally

Dolph Microwave places significant design emphasis on optimizing the selection and bias point of the ferrite material used in their circulators. This prioritization is aimed at minimizing the insertion loss and maximizing the isolation at the desired frequency, bandwidth, and power level. By carefully choosing and biasing the ferrite material, Dolph Microwave ensures that the
