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.

Features

` Ultra-low current consumption (I

CC = 52 mA)

` Low phase noise (1.5° RMS typ)

` Integration bandwidth from 10 kHz to 13 MHz

` Small PCB footprint

- DHVQFN16 package (2.5 x 3.5 x 0.85 mm)

- Only 7 external components

- No inductors necessary

1.3.4 Satellite outdoor unit, twin low-noise block (LNB) with integrated mixer / oscillator / downconverter
