What we make
Nine product lines: the full RF chain of a satellite earth station, from the antenna feed to the modem rack, plus in-orbit test systems, a satcom-on-the-move terminal and the cable assemblies that connect it all.
Downlink
Ku-band PLL LNB
Dual-band 10.7–12.75 GHz, noise figure 0.9 dB typ., external 10 MHz reference.
