3.6.2 FUNCTIONAL DESCRIPTION

Figure. 3.6.2 RECEIVER CHAIN BLOCK DIAGRAM 

3.6.2.1 Receiver
The X-GOLD™ 215 dual-band receiver is based on a Direct Conversion Receiver (DCR) architecture. Input 
impedance of the LNAs is optimized to achieve a matching without (external) high quality inductors. By use of 
frequency dividers (by 2/4) the LO frequency is derived from the RF frequency synthesizer. The receive path is 
fully differential to suppress the on-chip interferences and reduce DC-offsets. The analog chain of the receiver 
contains two LNAs (low/high band), a quadrature mixer followed by an analog baseband filter and 14-bit 
continuous-time delta-sigma analog-to-digital converter. The filtered and digitized signal is fed into the digital 
signal processing chain, which provides decimation, DC offset removal and programmable gain control.
