LINEAR INTEGRATED CIRCUIT
SINGLE LNB–BIAS, CONTROL
AND POWER MANAGEMENT
SOLUTION
DESCRIPTION
The UTC L8221 is a single chip power management and control
solution for LNB’s. The highly integrated solution provides all the
required FET and mixer bias, control detection and decoding, local
oscillator switching and a stable power supply for the IF amplifier
and additional support functions. Being at the heart of the LNB
monitoring the control, power management and environmental
conditions the UTC L8221 is able to provide reliable solution
eliminating effects such as false switching and over loading.
FEATURES
* Single chip LNB bias, control and power management
* 22kHz tone detector with signal rejection for band switching
* Zero Gate FET switching
* Integrated regulated supply for LNB
* Voltage detection for polarization switching
* Programmable mixer and FET bias
* Single pin for supply and control
* No external filtering required
* Temperature compensated protected FET bias
