The TFF1004HN is an integrated downconvertor for use in Low Noise Block (LNB) convertors in
a 10.7 GHz to 12.75 GHz Ku band satellite receiver system. This alignment-free concept replaces current solutions that require components such as GaAs mixer and DRO. As part of our LNB
chipset, it enables a Ku-band satellite receiver that lowers total cost of ownership and guarantees the stability of the local oscillator.

Application
4 Ku-band DVB-S receiver
Designedfor use in the Low Noise Block (LNB) of a Ku-band
satellite receiver for Asian and European standards, the NXP TFF1004HN is a highly integrated IC that includes an LNA, a mixer, a down-converter, a PLL, a crystal oscillator, and an IF buffer.
It is manufactured in NXP’s breakthrough SiGe BiCMOS
processfor microwave applications, which is more cost- effective than GaAs processes and more reliable than discrete implementations.
To comply with Asian and European DVB-S standards, the
TFF1004HN supports RF input frequencies between 10.7 and
12.75 GHz, and uses a selectable LO that operates at 9.75 or
10.6 GHz.
It is housed in a small HVQFN24 package that measures only
4 x 4 x 0.85 mm, and is designed to work as part of a complete chipset that provides a total LNB solution.
