Model ASC 902LE: Full Duplex 70 MHz to L-Band Converter

902pic

L-Band Up/Downconverter
Specifications

 

Functional Description:

The Model ASC902LE Full Duplex 70 MHz to L-Band Converter is a high performance unit that is a combination of  the model ASC501LE 70 MHz to L-Band Upconverter and the model ASC401LE L-Band to 70 MHz Downconverter modules installed in the ASCLE series single rack mount unit. The ASC902LE Converters independent design is  to up convert a 70 MHz  (52 to 88 MHz) base band input signal to the output frequency band of 950 to 1750 MHz and, simultaneously, down convert an input signal in the band of 950 to 1750 MHz to a 70 MHz output.

The upconverter and downconverter are two independent functions that are individually controlled from the front panel facilities.

The Model ASC501LE 70 MHz to L-Band Upconverter is a high performance unit that is designed to up convert a 70 MHz (52 to 88 MHz) base band input signal to the output frequency band of 950 to 1750 MHz. The output signal then may be interfaced to the final power stage of a satellite RF transmitter (SSPA or BUC). The system performance makes the ASC501LE ideal for low data rate applications. The half-rack width permits mounting two units side by side in one rack mount unit.

The Model ASC401LE L-Band to 70 MHz 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 half-rack width permits mounting two units side by side in one rack mount unit.
