Abstract :
A tunable RF filter for interference suppression applications, using a balanced passive complex mixer and a parallel LC tank load, is presented. The circuit has very wide dynamic range and zero dc-power consumption, and is designed for cognitive radio applications in the IEEE 802.22 system.
