A novel on‐chip RF choke at 5 GHz is designed and measured for a class A operating Wireless LAN RF power amplifier (PA). The coplanar waveguide (CPW)‐based on‐chip RF choke is implemented as an alternative component to inductors provided by the 0.35‐μm SiGe BiCMOS technology. The CPW RF choke is designed at 5 GHz, and has a length of 1600 μm and loaded with a capacitance of 0.95 pF. The measured impedance of the RF choke at 5 GHz is around 104 Ω. © 2007 Wiley Periodicals, Inc.
