The narrow-side oblique slit traveling slotted waveguide array antenna is designed to suppress cross-polarization through the dual design of choke groove and polarization grid. The product has the characteristics of high gain, low sidelobe, wide scanning angle and low cross-polarization. DH-SWRAX04-64-LPS-SMA is a weather resistant X-band slotted waveguide array antenna that operates from 8.2 to […]

Dolph Microwave manufactures a wide variety of standard rectangular to rectangular, and rectangular to circular waveguide transitions in overlapping bands to custom transitions spanning multiple bands. STANDARD FEATURES Frequency range of 0.35 GHz to 91.9 GHz Maximum VSWR as low as 1.05:1. Maximum Length: 1000mm. Waveguide transition sizes range from WR-2300 (0.35 GHz) to WR-12

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

This Ku-band transmit reject filter is designed for Ku band satcoms transmitter applications for suppressing broad band noise in the receive band from a transmitter output. It fully rejects the transmit band (above) and virtually all undesired transmissions (below) the receive band. Specifications: Model number: DH-120WBPF82PMA Rejectband: 13.75 –14.5 GHz Passband: 10.70-12.75 GHz Insertion Loss:

Dolph microwave offers seamless flexible/non-twistable waveguide, flexible twistable waveguide and hybrid flex/rigid waveguide assemblies from WR-22 to WR-650. and manufactured from a continuous length of thin walled copper/brass tubing. Its construction allows it to handle higher power levels than flexible twistable waveguide, and offers lower insertion and return loss. Key features Flexible Twistable sizes from

Each adaptor is tuned to offer the highest possible performance over the full waveguide frequency band. We have cooperated with a customer on a batch of WRD650 coaxial

C-Band Pass Filter play an important role in microwave circuits. Working attenuation is usually used to describe the amplitude characteristics of the filter, which is divided into: low-pass, high-pass, band-pass and band-reject filters. The amplitude-frequency characteristics of the four basic types of filters are shown below. APPLICATIONS Rejects terrestrial interference in C-Band (5G, Radar and
