Dolph microwave waveguide step twist provides accurate electrical and mechanical interface. Our compact step-twist exhibits a VSWR of less than 1.05:1 within 10% of the bandwidth. Lower VSWR or increased bandwidth can be achieved by using five-step warping. We also offer twist angles of 30, 45 and 60 degrees. Smaller sizes provide continuous or smooth […]

Dolph Microwave offers a wide variety of transmit reject and receive reject filters to reject uplink (or downlink) signals. By utilizing hybrid design techniques, the model DH-100WBPF95PPA bandpass filter is able to achieve extremely low through loss with deep transmit band rejection. Only 95mm in length. See below for WR90 X-band bandpass filter and electrical

  Please note that we will be closed during the New Year period of 2022 from January 1, 2022 to January 3, 2022. Normal trading hours will resume on Tuesday, January 4, 2022. Look forward to working with you throughout 2022! Sincerely.

Dolph Microwave offers a standard range of Waveguide Coaxial Transitions for Low-Loss Transmission up to 110 GHz. Waveguide Coaxial Transitions are good quality and economical. The Standard version is offered in Aluminium, Unpainted. Painted and Silver Plated (Brass) versions are available. It is possible to offer improved performance specifications for narrow band options. Additionally, these

WR75 Flexible Waveguide Section core starts life as a spool of 0.1mm thick, silver plated, brass strip. The strip is then precision rolled into a three-dimensional profile before being helically wound around a rotating mandrel to form a continuous rectangular tube with uniform cross section and internal silver plating to minimize loss. Flexible twistable waveguide

Dolph Microwave offers a standard product line of teflon/fiberglass high power pressure windows provide a seal within waveguide systems while passing microwave energy freely. The maintained pressure ensures maximum performance, and the seal prevents entry of moisture, dirt, and dust. These windows covering frequency from 0.3 to 112 GHz, the standard rectangular waveguide range from

Water Cooled Type waveguide tuners are waveguide components used to match the load impedance with the source impedance. They minimize the amount of reflected power, providing the most efficient coupling of power to the load. Dolph Microwave supplies both manual 3- and 4-stub tuners, electrical and auto tuners. Tuners utilize manual tuning and lock simply.

Dolph Microwave manufactures loop couplers covering a wide frequency range. Multiple flange and coaxial connector types and configurations are available. It’s ideal for RF microwave applications where high power sensing is desired. It features small volume, low VSWR, low frequency response and major waveguide bandwidth. The coupling level can be custom made ranging from 30

Waveguide Rotary Joints (rotary couplers) are used to transmit microwave energy from stationary lines to rotating lines. The Ku-band waveguide rotary joint is an electro-mechanical device with RF performance dependent upon rigorous electrical and mechanical design. Available styles are defined by physical geometry as follows: I- style, II- L-style, III- U-style. Please call us and
