Abstract

This paper presents a new methodologie of a decimator filter design in a multistandard receiver architecture for WiFi and Bluetooth. This filter must satisfy the specifications of a fifth DeltaSigma complex bandpass modulator which operates at a sample rate of 160 MHz. The function of the decimator filter is to make the channel digital selection for duo standards WiFi (IEEE 802.11g) and Bluetooth (IEEE 802.15.1). In other hand, a digital down converter is necessary to make a frequency translation in baseband.
