A FIR baseband filter for high data rate 60-GHz wireless communications

A 4× oversampling 18
^th
order digital FIR filter suitable to replace all analog baseband filters in a mobile high-data-rate wireless communication transmitter is presented. Special architecture optimizations allow an estimated output sampling rate of 10Gs/s in 65nm CMOS while respecting full spectrum mask specifications of the ECMA & IEEE standards over the radio band of 8 GHz.
