Abstract

The miniature millimeter-wave integrated circuit LO/mixer assembly was developed with over the full waveguide band coverage and good temperature stability. A conversion loss of less than 7 dB was achieved over 16 GHz instantaneous IF frequency with the RF swept from 30 to 46 GHz and the LO at 48 GHz. With another mixer, when the RF was swept from 18 to 30 GHz and the LO was at 32 GHz, similar results were achieved. Using resonant stub and dielectric temperature compensation produced good temperature stability.

微型毫米波集成电路宽带下变频器
开发了微型毫米波集成电路LO/混频器组件,具有全波导覆盖和良好的温度稳定性。在16 GHz瞬时中频频率下,射频扫频范围为30至46 GHz,本端为48 GHz,转换损耗小于7 dB。使用另一个混频器,当射频从18 GHz扫频到30 GHz,本端为32 GHz时,获得了类似的结果。采用谐振短段和介质温度补偿产生了良好的温度稳定性。
