AZ730 Up & Down-converter

The Newtec Azimuth Series AZ730 is a high performance Up & Down frequency converter designed for a wide range of broadcast, telco and IP satellite applications

In its default configuration, the AZ730 upconverts IF signals (70 or 140 MHz) to L-Band (950–1750 MHz) and simultaneously downconverts L-Band signals (950–2150 MHz) to IF. Optionally, the AZ730 can upconvert IF signals to C, Ku or DBS-band.

The AZ730 offers some advanced and unique features such as a calibrated high linearity over the entire bandwidth combined with a very high frequency stability. These features make the AZ730 the perfect solution for a wide range of transmissions ranging from very small carriers to full transponder applications.

The IF frequency is switchable from 70 MHz to 140 MHz and the L-Band frequency is adjustable in steps of 48 Hz.

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.

A 24V DC power supply and a reference frequency on the L-Band output are also available as options, providing a compact and cost effective solution when the AZ730 is used in combination with an outdoor RF upconverter and/or amplifier.

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.

The AZ730 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 AZ730 via RMCP or SNMP.
