Description:

The Model 2400-HAMTV-DC is a low noise, high gain, high linearity down converter designed for digital TV applications. It is specifically designed to down convert the 2422 and 2437 MHz DVB-S signals from the planned 2.4 GHz HAMTV on the International Space Station to a suitable DVB-S satellite receiver.


The down converter is suitable for all digital TV-modulation like DVBS - DVBT - COFDM - QPSK  because of its high linearity, good frequency stability and low phase noise oscillator.


The down converter can be used with the readily available free-to-air DVB-S receivers which tune from 950 to 2150 MHz.


Using the internal 916.5 MHz SAW oscillator, the down converter IF output will be 1505.5 MHz for the 2422 MHz signal and 1520.5 MHz for the 2437 MHz signal. The DVB-S receiver can also be used to power the down converter through the IF output cable.


The converter is usable over its input bandwidth of 2350 to 2450 MHz.
