Functional Description

The Model ASC501LE Up Converter 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 1525 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 LE Series half-rack width permits mounting ether two of the same units or a combination of our ASC501LE Up Converter and our ASC401LE Down Converter (Model ASC902LE) side by side in one rack mount unit.
