摘要：

A miniature broad-band balanced frequency doubler has been designed to operate from 30 to 50 GHz. It comprises a reduced-size 180degrees rat-race hybrid and two distributed doublers to form a balanced doubler configuration. The balanced distributed doubler suppresses the 1801 out-of-phase fundamental and third harmonic signals at the output. port while combining the in-phase second harmonic signal. A measured conversion loss of 5-7 AB from 30- to 50-GHz output frequencies is achieved with fundamental and third harmonic signals rejection better than 13 and 25 dB, respectively. The chip size is only 1.5 x 1 mm(2).
