This paper presents a MMIC direct conversion receiver for WLAN manufactured in SiGe: C BiCMOS technology for the IEEE 802.11a/HiperLAN WLAN standard. Direct conversion architecture was chosen because it eliminates the need for bulky external image reject filters, resulting in a compact, low power and low cost front-end. The direct conversion receiver must incorporate quadrature downconversion as both lateral bands contain different information that will be distorted if they are superimposed.
