【 摘 要 】

References(10)A multifunction circuit to simplify a multiband front-end operating at very different bands is proposed. The multifunction circuit operates as a sub-harmonic mixer or an attenuator depending on a control voltage. A multiband front-end using the proposed multifunction circuit can reduce component, is 23 percent smaller, and is less expensive compared to a conventional architecture with a switching circuit.
