May 28th, 2023 – Xi’an, SHAANXI – Dolph Microave, a design and manufacturer of superior waveguide components, antennas – is pleased to announce to announce the completion of the design and production of the 8-18GHz WRD650 waveguide isolator, It use a Y-junction structure housed in standard double ridge waveguide with one addition of a matched […]

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 circulators

Block type directional couplers are passive devices mainly used in the field of wireless technology. They couple the defined amount of electromagnetic power in the transmission line to the port, allowing the signal to be used in another circuit. Dolph Microwave’s DH-900WBDC25PPPPC broadband directional coupler is a wide walled porous energy coupling device operating in the

Dolph Microwave manufactures standard gain horn antennas specifically designs for utilization in emissions and immunity testing over the frequency range of 0.32 to 110 GHz. And, they offer high power handling capability, and low loss, also high directivity, and near constant electrical performance across a wide bandwidth, low gain variation across their operating frequency. In

Dolph Microwave waveguide to coaxial adapter (also known as a waveguide coaxial transition) is manufactured with a right angle design. Right angle waveguide to coaxial adapter / transition has a waveguide size of WR-340 and UDR cover flange. This WR-340 waveguide to coax adapter / transition is constructed with a SMA coaxial connector that is

The log-periodic antenna is the main preferred form of the low-frequency UWB directional antenna. This antenna family has the remarkable capability to cover octave bandwidth or even UWB bandwidth of nearly 100 octaves. With a potential gain of up to 9 dB, it offers a significant boost to signal reception and transmission. At ultra-low frequencies,

A circular waveguide refers to a waveguide with a circular cross-section. The lowest order propagation mode in a circular waveguide is TE11, which provides minimal signal degradation. The possible TM modes in circular waveguides are TM01, TM02, TM11, and TM12. The modes maintained by circular waveguides have many similarities with those of rectangular waveguides. For

WR284 Rectangular to Circular WG Transition (TE10-TE11) Adapter is suitable for S-Band Magnetron Transition Adapter.
