Newtec Azimuth Series AZ720 L-Band Downconverter
Internal 10 MHz reference, High Stability Frequency Conversion
AZ720 L-Band to IF Downconverter
This product has reached end of life and has been replaced by the Newtec FRC0720
The Newtec Azimuth AZ720 is a high performance L-band to IF frequency downconverter designed for a wide range of broadcast, telco and IP satellite applications. The AZ720 offers some advanced and unique features such as a calibrated high linearity over the entire bandwidth combined with a very high frequency stability.
The AZ720 has a very wide gain range and a low noise figure which makes it suitable for the conversion of narrow and broadband L-band signals to IF. The L-band input frequency is adjustable over the range of 950 MHz up to 2150 MHz. The IF output frequency is switchable between 70 MHz and 140 MHz.
The high output frequency stability is provided by an internal 10 MHz reference clock. For applications requiring a very high frequency stability such as very low data rate carriers, an optional reference clock of 0,01ppm can be ordered separately.
Built-in LNB Power
Optionally, an LNB power supply, a frequency band selection signal and a 10MHz reference frequency can be delivered to an LNB via the L-band input providing a compact and cost effective solution.
The AZ720 is easy to operate and monitor. All control and monitoring parameters are available locally on the front panel and remotely through a web interface. It is also possible to control or monitor the AZ710 via RMCP or SNMP.
