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

Dolph Microwave offers a line of waveguide pressure windows to mate with all standard waveguide flanges. and it is covering frequency from 0.3 to 110 GHz, as well as, the standard rectangular waveguide range from BJ3 to BJ900, and the typical VSWR is 1.25 over the full waveguide bandwidth, and typical insertion loss is 0.2

The Dolph Microwave teflon/fiberglass 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. The window allows sealing environments under vacuum (plasma application), One side negative pressure and the other side positive pressure, at high pressure

Dolph Microwave manufactures a series of high-performance Waveguide Flange Shim, applying to a rectangular waveguide type, flat rectangular, moderately flat rectangle, square,round, single ridged and double ridged standard type, etc. The frequency range is from 0.3 to 110 GHz. The standard rectangular waveguide range from BJ3 to BJ900, the typical VSWR is 1.03 over the

To address Ka-Band satellite-on-the-move (SOTM) requirements, Dolph Microwave has added WR28 Dual-Channel Rotary Joint model DH-320WRJUIPMA to its family of microwave rotary joints. This miniature dual-channel device features a high-power transmit channel implemented in a right-angle WR28 waveguide on the fixed (input) side and a female K-type coaxial connector on the rotating (output) side, while
