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.
