Satcomms test loop translators target X-band


A series of satcomms test loop translators for use in X-band has been released by AtlanTecRF. The devices provide direct frequency conversion either from Tx to Rx, Tx to L-band or from L-band to Rx in the nominal frequency ranges of 7.9-8.4GHz Tx and 7.25-7.75GHz Rx.

The translation of the 500MHz band is achieved with double balanced mixing and usually a fixed frequency local oscillator. Although, if frequencies outside this nominal band are required for the same 950-1450MHz L-band, there is a standard option to specify a synthesised variable frequency local oscillator.

Each unit comes with the choice of either a manually or digitally controlled attenuator. The manually controlled, front panel mounted, variable attenuator operates across a 30dB range in order to back-off the input signal to a manageable level. For both local and remote operation, the digitally controlled attenuator operates up to 64dB in steps as low as 0.25dB.

Users can control the frequency and attenuation of the translators either directly via the front panel or remotely via Ethernet. Specification options include switchable internal and external 10MHz reference frequency, 0dB conversion gain, coaxial or waveguide input and output connectors, 19” 1U rack mount or weatherproof outdoor housings, high isolation input/output filtering and a premium phase noise local oscillator.

Standard input power is 80-240VAC but there are also options for DC input and for the device to be fully portable with internal rechargeable batteries. Dual redundant diode controlled power supplies are also available as a standard option.

Geoff Burling, AtlanTecRF, CEO, said: “There are many key satcomm users in the X-band and for these we can now offer all the same facilities and options as those in the more popular C, Ku and Ka bands”.
