1. general description the TFF1044HN is a 10.70 ghz to 12.75 ghz k u band down converter for use in universal quad and quattro low noise bloc k (lnb) in satellite re ceiver systems. the device features two rf inputs (two polarizati ons) and four if outputs (up to 4 active if paths). it integrates bias generation and c ontrol for the required external lna stages, image rejection filtering, lo generation, down-conversion mixers, if amplifier stages, voltage and tone detection on each if output (for polarization and band selection) and the 4 (if channels) ? 4 (2 polarizations, 2 bands) if matr ix switch. for flexibility, the gain can be controlled in three discrete stages, the po larization of the rf inputs can be swapped and the second stage lna biasing control can be switched from phemt to bjt configuration. 2. features and benefits ? low current consumption integrated pre-amplifier, mixer, buffer amplifier and pll synthesizer ? integrated phemt/bjt bias control for external lnas ? flat gain over frequency ? single 5 v supply pin ? operates with a low cost 25 mhz crystal ? crystal-controlled lo frequency generation, alignment free concept ? dual simultaneously operating lo frequencies (9.75 ghz and 10.6 ghz) ? adjustable step gain (30 db, 33 db and 36 db) ? integrated s witch matrix ? integrated voltage and tone detector ? low phase noise ? low spurious ? low external component count ? alignment-free concept ? 36-terminal leadless plastic thermally enha nced very thin profile land grid array package 5.0 mm ? 5.0 mm ? 0.72 mm 3. applications ? quad lnbs ? quattro lnbs ? ip lnbs TFF1044HN integrated mixer oscillator pll for satellite quad lnb rev. 1 ? 10 june 2015 product data sheet + 9 / * $
