NXP Semiconductors says it has introduced the industry's first fully integrated downconverter for Ku-band DVB-S low-noise block (LNB). The TFF1004HN RFIC was developed with Andrew Corp. for its satellite LNB.

Designed for the LNB of DVB-S receivers, which are typically used by commercial satellite TV operators and TV networks for remote broadcasting, the TFF1004HN is made using NXP's advanced QUBiC4G SiGe BiCMOS process, which eliminates the need for manual local oscillator alignment.

As part of NXP's complete LNB chipset, customers will benefit from the savings in total cost of ownership and guaranteed stability of the local oscillator, NXP said. In addition, the chip is housed in an HVQFN24 package that measures only 4mm x 4mm x 0.85mm.

Supporting RF input frequencies of between 10.7GHz and 12.7GHz, and using a selectable LO operating at 9.75GHz or 10.6GHz, the TFF1004HN complies with Asian and European standards. Development of a U.S.-compliant TFF1004HN is in the works.
