ANTENNA FEEDS & RF NETWORKS
Dolph Microwave offers the high performance and high quality antenna feeds and RF networks to enable satcom antenna to offer the best performance. The antenna feed and RF networks are all components combination of antenna used for RF waves receiving and Transmitting. The antenna feed is portion of the antenna ranging from the Tx range to the receive range. The antenna waveguide feed includes transforming the RF waves into electrical signals and transmitting them to the receiver components. So it is namely used for the conversion RF waves into the electric signals.

Types of Antenna Feeds & RF Networks
Antenna feeds and RF networks as the heart of antenna system from Dolph Microwave is R&D by experienced our engineers who engaged into satcom and RF field for years. The components can be offered including OMT, duplixer, filter, phase shifter and feedhorn etc. covering different bands like C-band, Ku-band, Ka-band, S-band. X-band and required dual band etc. Any requirement, please contact sales@dolphmicrowave.com

Antenna Feed Point Impedance
For an antenna feeds design, the efficiency, gain, and absolute gain are very important.

The feed impedance includes the loss resistance and the radiation resistance. The loss resistance is offered by the antenna components and the feed impedance is at the input of the antenna to the signal. Thus, the loss and the feed impedance must work together to achieve antennae feed normally work.
