Abstract:

This paper introduces the circuit simulation and design of an X-band fourth-harmonic mixer based on the anti-paralleled Schottky diodes pair.It has been found that a gentle variance in the LO power or RF power can lead to a sharp change of the IF signal phase.According to the discovery,the whole system is improved.The test results demonstrate the feasibility and good performance of the improved circuit.

Key words: X-band;harmonic mixer;Schottky diode;phase characteristic
