9900 Series Frequency Converters
The MITEQ frequency converters are designed for advanced
satellite communication systems and are available for a wide
variety of frequency plans. Phase noise, amplitude flatness
and spurious outputs have been optimized to provide the user
with a transparent frequency conversion for all video and data
applications.
A strong feature set of monitor and control functions supports
powerful local and remote control. Among the features are
control of frequency, attenuation and 64 memory locations for
each converter where various setups can be stored and
recalled.
A continuously updated log of time-stamped records of activity
is also provided.
Features
• Supports expandable NSU 1:N Switchover
Series (D-323)

Analog reference Phase Lock: External 5 or 10 MHz at +4 ±3 dBm. If external reference is below +1 dBm nominal, the
converter will automatically lock to the internal reference. Reference oscillator acts as an analog phase lock with a 0.1 Hz
nominal loop bandwidth. Typical loop suppression of the external reference is as follows: 28 dB at 1 Hz offset; 65 dB at
10 Hz offset and 100 dB at 100 Hz offset.
