Local oscillator and mixer assembly |
摘要 |
A radio-frequency mixer and a local oscillator integrated into a single housing, and including a Gunn-type oscillator coupled to the mixer by a section of microstrip transmission line and a section of suspended stripline. A broadside coupler in the suspended stripline provides dc and intermediate-frequency isolation for the mixer, and a block of dielectric material on the microstrip provides improved temperature compensation for the diode oscillator. The entire compact assembly has good conversion loss performance over a relatively wide frequency band, and is relatively insensitive to temperature changes.
