At the Satellite 2016 Show, AtlanTecRF launched its new ground breaking Ka Band Satellite Simulator. The LSS range of ‘game-changing’ Satellite Simulators are designed for operation in Ka band with optional use in other bands, including Ku and DBS.
Satellite simulation is derived from a unique microwave architecture which provides translation of uplink to downlink frequencies of a mobile satcom system without the need for cabling on either the test site or on location. The new Ka Band Satellite Simulator from AtlanTecRF is totally self-contained. It is powered by internal rechargeable batteries with 24 hour duration, thereby permitting the unit to be set up within transmit range for a fully functional RF test in both left and right hand circular polarisations.
Interface with the system under test is facilitated with a pair of 15dB gain horn antennae, one for reception of the uplink signal and one for transmission of the downlink signal and the conversion gain within the satellite simulator is -35dB. Adjustment of the signal within both the transmit and the receive paths is achieved by manual 30dB continuously variable attenuators.
In addition to the base instrument there are a series of performance enhancing options such as synthesised LO frequencies for greater versatility, digitally controlled signal attenuators with LCD readout and 0.25dB resolution. All instruments, as part of the self-contained series, include a high stability OCXO reference oscillator with less than 0.002PPM variation in frequency over the operating temperature range of 0 to +40C.
Fixed frequency LO units have a choice of either 9.80 or 10.30GHz local oscillator while the synthesised option covers 8.80 to 10.95 GHz in 25 MHz steps or finer increments if required.
The overall size of this very portable satellite simulator is just 260 x 150 x 420 mm and it is fitted with a convenient carry handle which also serves to set the beam angle for optimum test conditions.
