Improving Warm-up Time and Frequency Stability of Microwave Bricks

摘要

This may be old news given the time bricks have been around and in use, but here's an easy modification you can apply to most bricks that will reduce it's warm-up time and drift at power up. The modification also improves frequency stability. This is done by separating and independently switching and regulating the DC power going to the crystal oscillator/oven board. I performed this modification to two 10GHz bricks with similar results.
