摘要

实验研究了一种用于60ghz频段合成本振的次谐波注入锁定MMIC谐波压控振荡器。使用HBT mmic的设计是基于使用谐波压控振荡器的2次谐波注入锁定，上变频到毫米波频率，并扩大锁定范围。使用来自压控振荡器的四次谐波信号可以使锁定范围增加八倍。采用折光型负载电路的传输型注入锁相MMIC压控振荡器不仅增加了锁相范围，而且提高了锁相压控振荡器输出的高次谐波输出功率。

Millimeter-wave HBT MMIC synthesizers using subharmonically injection-locked oscillators

A subharmonically injection-locked MMIC harmonic VCO for use as a synthesized local oscillator in the 60 GHz band has been experimentally investigated. The designs using HBT MMICs are based on the use of 2nd subharmonic injection locking of the harmonic VCOs to upconvert to millimeter-wave frequency and broaden the locking range. The use of the 4th harmonic signal from the VCOs allows a factor of eight increase in the locking range. The transmission type injection-locked MMIC VCO with the refractive type load circuit increases not only the locking range, but also the high-order harmonic output power in the locked VCO output.
