4.5cm broad band C/X secondary focus receiver (4000-9300 MHz)

This is a broad-band receiver with two orthogonal linear polarizations (at a 45°-angle with the horizon). The system is still under test, but could be used on a "shared-risk" basis.

normalized Gain curve (G = A0 + A1·Elv + A2·Elv2) Observed in confirmed
A0 = 0.9928A1 = 4.212E-4A2 = -6.158E-6Jun 2016

Comments:

  • The gain curve was corrected for opacity (though it is small, < 0.02 throughout the band).
