Product highlight:
Industry’s lowest-power integrated Ku-band downconverters
These Universal DVB-S compliant Ku-band downconverters consume
about 50% less current (52 mA) than other integrated solutions.
They are fully integrated (PLL synthesizer/mixer/IF gain block) and RF
tested – which results in significantly decreased manufacturing time.
Stability of the local oscillator is guaranteed, which improves overall
system reliability over temperature and time, and eliminates the need
for manual alignment in production.
