Description
The SL1914 is a wideband LNA with AGC designed
primarily for application in satellite tuner front ends,
offering high signal handling capability with low noise
figure compatible with most common tuner input
requirements.
The SL1914 is optimised to complement the SL1925,
ZIF quadrature downconverter, integrating all the active
RF circuitry within the tuner, in a highly compact, efficient
solution, and offering a full 1-45 MS/s tuner capability.
