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-m SiGe BiCMOS technology. The CPW RF choke is designed at 5 GHz, and has a length of 1600 m and loaded with a capacitance of 0.95 pF. The measured impedance of the RF choke at 5 GHz is around 104 .
