LONDON NXP Semiconductors and Andrew Corporation have collaborated on the development of a fully integrated down converter for Ku-band digital video broadcasting satellite Low Noise Blocks (LNB).
The device, said to be the first fully integrated silicon based IC for satellite LNBs, is being made on NXP’s QUBiC4G SiGe BiCMOS process.
The companies say the RF IC, dubbed the TFF1004HN, is far more cost effective than current discrete solutions using GaAs components and dielectric resonator oscillator (DRO).
The part is already being deployed in the LNB of Andrew Corporation's latest DVB-S receivers.
"The introduction of the TFF1004HN is a major milestone in satellite receiver technology," said Ron Schiltmans, engineering manager, Andrew Corporation.
"Over the past years, we’ve worked closely with NXP during the definition and development of the TFF1004HN. NXP's highly integrated IC offers the benefits of stability and reliability that discrete solutions can not offer, whilst simultaneously maintaining a low total cost of ownership."
The chip, which has started sampling, is housed in an HVQFN24 package that measures 4x4x0.85 mm, allowing for the smallest total LNB footprint when used as part of the complete NXP LNB solution.
It supports RF input frequencies between 10.7 and 12.7 GHz, and using a selectable LO operating at 9.75 or 10.6 GHz, the TFF1004HN complies with Asian and European standards. A U.S. compliant version is under development.
