| Summary: | Wireless communications are integral to modern technology, particularly as telecommunications innovations have rapidly progressed over last half of twentieth century. The demand for wireless local area network (W LAN) hardware has surged in recent years, driven by advancements in transmission speeds, coverage areas, security, quality of service (QoS), and mobility resulting from continuous evolution of WLAN technology. A wireless communication system's transmitter architecture, transmission rate, and receiver architecture are all determined by wireless communication channel. Since establishment of IEEE 802.11 protocol, WLANs have undergone significant transformation over past two decades, reflecting the increasing demand for their services. IEEE 802.11 standard specifies physical layer for communication across a local area network that is wireless across frequency ranges of 2.4, 3.6, 5, and 60 GHz. Wi-Fi primarily operates within multiple frequency bands, such as 2.4 GHz and 5 GHz, offering a variety of channels to accommodate multiple devices in diverse environments. This work aims to design a radio frequency synthesizer characterized by high speed and minimal noise. The results obtained show that when it relates to producing high-output signals with little spur noise, the second frequency synthesis that was suggested performs superior. At a 2 MHz frequency offset, the phase measurements of noise for 2.4 GHz register at -155.799 dBc/Hz, and at a 3 MHz frequency offset, they reach -170.596 dBc/Hz, which is within the permitted range. Additionally, synthesizer achieves an improved settling time of 6.320 μs
