CXA3685ER Overview
The CXA3685ER is an IC developed for direct orthogonal detection of L band (1 to 2GHz) IF signals in a digital satellite broadcast reception tuner. This direct conversion (Zero-IF) technology eliminates the need for the SAW filter that was formerly necessary. In addition, the CXA3685ER incorporates an RF gain control amplifier, oscillator circuit, wide-band phase shifter circuit and other RF circuits, a baseband...
