受美国疫情影响，Marki Microwave暂时关闭了工厂，改为在家办公，预计持续到5月份。具体开工时间也等当地政府通知，所以近期Marki订货影响比较大，有现货要4-6周，没有现货要16周。

在家办公，在线学习。Marki开展了一系列在线研讨会，有兴趣的朋友可以点击下文链接，报名参加。

由于时差，如果不能及时在线参加也没关系，点击以下链接，可查看录播视频。

Webinar: Microwave Amplifier Biasing Made Easy
April 16, 2020 | 10 am PST
对应北京时间：4月17日凌晨1点
 
Optimal amplifier biasing can make a direct impact on the performance of your system. However, choosing the correct bias levels for your application can be challenging, and there are a number of factors that are often overlooked. In this short (25 minutes) webinar, Marki Microwave will provide insight into:

• Important distinctions between amplifier topologies

• Biasing considerations to improve noise filtering, reliability, and electrical performance

• Heat: why it's a stronger factor than you might think

 
Webinar: A Brief Guide to Mixer Spurs
April 30, 2020 | 8 am PST
对应北京时间：4月30日23点
 
Spurious products can quickly overcrowd your output spectrum and destroy the dynamic range of your system if you aren't careful. The threat of these spurs can be minimized if a designer can predict their exact frequency and power early in the design phase. In this short (25 minute) webinar, Marki Microwave will discuss:

• Where single tone intermodulation products come from within a mixer

• How to model a mixer to get close approximations of spurious levels

• How to get the most accurate prediction possible without sitting in front of a VNA
