These products – the integrated downconverters TFF101xHN,

the wideband transistors BFU710F/730F for LNA and mixer

functionality, and the BGA28xx series of IF MMICs – are

the most recent additions to NXP’s leading portfolio for

satellite LNB. They join the other discrete products, including

oscillators, amplifiers, and switches, to provide complete

coverage for all LNB architectures.

Since the ICs, transistors, and the MMICs are manufactured

in NXP’s industry-leading QUBiC4X SiGe:C and QUBiC4+

process, they offer better overall RF performance and are more

robust than their GaAs equivalents and offer the added cost

advantage of silicon. The process technology also enables

higher integration, for added features. NXP owns the industrial

base for production (wafer fab, test, assembly), so volume

supplies can be assured.
