•
•
Low oscillator phase noise and reradiation.
High output referred linearity for low distortion and
multi channel application.
The SL1935 is a complete single chip
bus controlled
I C
Zero IF tuner and operates from 950 to 2150MHz. It
includes an on-board low phase noise PLL frequency
synthesiser and low noise LNA/AGC. The SL1935 is
intendedprimarilyforapplicationindigitalsatellite Network
Interface Modules and performs the complete tuner
function.
