Ka Band Satellite Transmitter

Ka band and downconverted to the intermediate frequency required by the modem input.

Ka band satellite transmitter.

The front end is the usual direct tv ka band lna. Ka band dishes can be much smaller and typically range from 60cm 1 2m 2 to 4 in diameter. Yet bringing connectivity to remote locations such as rural areas or the open sea remains difficult. General dynamics hrt150 ku band transmitter provides a solution for delivering large amounts of data from a spacecraft in one small package.

Our ka band gateways are part of a complete broadband system offered by viasat. State of the art high reliability ka band transmitter providing very flexible high data rate capability while incorporating advanced digital modulation schemes. Frequency coverage will include 27 to 30 5 ghz for uplink communications and 17 to 21 2 ghz for downlink communications. Fully frequency agile and on orbit reconfigurable.

Communications technologies have reached unprecedented levels of advancement. The lna has retained the existing ka band feed and now provides lhc and rhc outputs on sma connectors. Transmission power is much greater compared to the c x or ku band beams. In satellite communications the k a band allows higher bandwidth communication.

The direct tv ka lnb has been chopped in half to produce two lna units. Greater connectedness in remote areas. The le katr 102 transceiver is a fully populated pcb designed to fit within a 1u cubesat profile 100 100 100 mm. The ka band k band above is primarily used for two way consumer broadband and military networks.

It was first used in the experimental acts gigabit satellite network and is currently used in the inmarsat i 5 system and the spacex starlink system and will be used in the iridium next satellite series kacific k 1 satellite as well as the james webb space.
