Frequency range 2 to 18 GHz Gain 65, 70 or 80 dB max Digital attenuator on 8 bits 0 to 32 dB by step of 0.125 dB DC power supply 9/36 V 1.3 A Working temperature 0 to +50°C Dimensions 129 x 110mm h=62mm The gain will be adjustable with the attenuator command, in order to obtain the requested R.C.S. Measurements Each unit is delivered with 2 gain patterns for attenuator adjusted to 0 and 20dB. Options Supply of circular polarization wide band antennas with +/-80° of aperture Supply of rectilinear polarization narrow band antennas with +/-70° of aperture Supply of antennas to specification (rectilinear or circular polarization) Supply of cables (length upon request) Filters: low pass, high pass, band pass between 4 and 18GHz Usage precautions In order to avoid coupling, the antennas must be at least 1 m apart with minimum of 100mm between axes.
