Description

The STA011 is an RF IC using

STMicroelectronics BiCMOS6G high speed

technology for one chip solution for the digital

satellite radio receiver. The STA011 is assembled

in a TQFP44 package. The front-end architecture

is a double conversion receiver (see block

diagram). The chip includes all the RF functions

up to low IF and it manages the signals going to

and coming from the base-band.
