    WANGKE, chief engineer of satellite application department, introduced the newly designed and improved S/X/Ka Tir-band feed, which is a typical representative of the integration of TT&C data transmission. The feed has three-band downlink data receiving capability and S-band upstream data transmitting capability. It has the characteristics of multi-band, broadband, polarization multiplexing and high […]

  Dolph Microwave 1.2 Meter driveaway antenna for Ku/Ka dual band . Rugged packaging, robust wind performance, ease of operation and post-delivery customer support at a very competitive price.   1.2 Meter driveaway antenna is capable of transmitting and receiving in Ku/Ka-band frequencies simultaneously. and quick deploy with operational status achieved in less than 10

  The ring- focus antenna is usually called the parabolic focal axis offset axisymmetric dual mirror antenna. Since the focal trajectory of the antenna is a circle, it is called the circular focus antenna.     The ring-focus antenna has its unique position in the satellite communication earth station antenna. Especially in the small and

  Quad-Ridged Horn Antenna is one of the wide-band antennas developed by Dolph Microwave. It covers different combined frequency bands within 0.1-40GHz, and is widely used in EMI / RFI testing, evaluation, and electronic monitoring. It can also be used as a feed for high-gain parabolic reflector antennas used in directional and monitoring.   Because

    The logarithmic periodic antenna is the main preferred form of the low frequency uwb directional antenna. The antenna family can cover octave bandwidth or even uwb bandwidth of nearly 100 octaves. The gain can be as high as 9dB. At ultra-low frequencies, a hybrid design is adopted to achieve a high integration of

Waveguide Components Composite Dolph Microwave offers one of the most complete lines of composite twist-bends waveguide in the industry. Basic styles in many bends include miter and radius 90 bends, as well as acute and obtuse E and H plane bends in angles from 30 to 180. Our dual-E and offset bends were developed to

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:
