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: […]

We have cooperated with a customer on a batch of X-band high power waveguide terminations for radar system recently. Following is the product details before surface treatment and VSWR test which is ≤1.05:1. Features Waveguide terminations WR-22 to WR-650 Air cooling, water cooled and water terminations available. Units pressure tested to 30 psi. Low outgassing

  In order to provide the fastest products and services to our customers, Dolph Microwave stocked a series of products flexible twistable waveguide; the fastest delivery is on next day.     Flexible Twistable Waveguide   – Model: DH-137WEL1000MMC   – Freq.

  DH 3.7m ESA Antenna Systems has finished delivery and test for customer, which is for satellite broadcast TV receive and transit services. Dolph Microwave also offered Tx transmit waveguide kits and RF device besides antenna.   DH 3.7 Meter DR C-band Antenna   It uses Eutelsat satellite as signal transfer, who has strict requirement

Dolph Microwave the precision version double ridge WG coax adapters is manufactured from brass or aluminum and painted with attractive, hard wearing, epoxy paint finish as standard. 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

  Dolph Microwave have resumed production and delivered the order products ASAP, Most waveguide components delivery lead time are still within 4 weeks. welcome any requirement.     Delivered waveguide coaxial adapter details for your reference.            

    With the 5G cellular base station testing and large-scale deployment of mobile communication operators. The interference of the 5G spectrum with the FSS Ext.C band (3.4-3.7 GHz) or the standard C band (3.7-4.2 GHz) will become more and more serious.   To solve the problem of co-channel interference and adjacent-channel interference in the

    In the 3GPP protocol,the overall spectrum resources of 5G can be divided into two FR (Frequency Range)   FR1: The Sub6G frequency band is the main frequency band of 5G and is a low-frequency band，the frequency below 3GHz is Sub3G, and the remaining frequency bands are called C-bands. FR2: Millimeter wave is an
