The cell includes matched input, intermediate and output buffers with gain control, separated quadrature mixers and polyphase filter. Quadrature mixer is based on Gilbert cells and converts RF frequency to a low intermediate frequency (IF). Polyphase filter is used to block image
frequency signal. Buffer amplifiers are used to improve qualitative characteristics, reduce input signals and improve output signals, reduce rejection, harmonic and intermodulation distortions.
The block is fabricated on SMIC CMOS 0.18 um technology.
