    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:
