Abstract :
For the first time, an analytical formula is presented for calculating the OIP3 of any arbitrary circuit with a single shunt varactor diode. Additionally, numerical calculation of the limits on varactor tuning range when a specific OIP3 is desired is discussed, and a commercial varactor is found to maintain 44% of its tuning range with a OIP3 > 37 dBm.
