Datasheet

1. General description
The TFF1018HN/N1 is an integrated downconverter for use in Low Noise Block (LNB)
convertors in a 10.7 GHz to 12.75 GHz K
u
band satellite receiver system.
2. Features and benefits
 Low current consumption integrated pre-amplifier, mixer, buffer amplifier and
PLL synthesizer
 Flat gain over frequency
 Single 5 V supply pin
 Low cost 25 MHz crystal
 Crystal controlled LO frequency generation
 Switched LO frequency (9.75 GHz and 10.6 GHz)
 Low phase noise
 Low spurious
 Low external component count
 Alignment-free concept
 ESD protection on all pins
3. Applications
 K
u
band LNB converters for digital satellite reception (DVB-S / DVB-S2)
