Model ASC401LE: L-Band to 70 MHz Downconverter (950 - 1750 MHz)

Other Frequencies Available

401pic

L-Band to 70 MHz Downconverter Technical Specifications
 

Functional Description:

The Model ASC401LE L-Band to 70MHz Downconverter is a high performance unit that is designed to down convert an input signal in the frequency band of 950 to 1750 MHz to the 70 MHz (52 to 88 MHz) base band output. The output signal then may be interfaced to an external 70 MHz customer supplied receive equipment. The LE Series half-rack width permits mounting ether two of the same units or a combination of our ASC401LE L-Band to 70MHz Downconverter and our ASC501LE 70 MHz to L-Band Up Converter (Model ASC902LE) side by side in one rack mount unit.
