Modular Frequency Up Conversion For Antenna Ranges

A distributed RF subsystem is a common solution for antenna test ranges where dynamic range is to be optimized. This is especially relevant for electrically large1 systems since cable losses become prohibitive. For such solutions the locations of the components comprising the RF subsystem are critical. By using remote mixers, amplifiers and multipliers, the use of lower frequency cables with lower loss becomes feasible and this approach dramatically increases the available power level at the transmitting antenna and the sensitivity of the receiver.
