关于射频晶体管 SD2933的相关技术问题

我们想用这款晶体管驱动在900KHz、1.7MHz、3MHz条件下压电陶瓷,需要50W左右的功率。我有以下几个问题需要帮助:1、这款晶体管能否应用于900kHz的频率,是否只能应用于1MHz以上的频段?2、数据手册里提供了30MHz条件下的测试电路,其中的FB2与T2元件的作用与原理我们不是十分理解,能否讲解一下?我们猜测该组件的作用应该是起到阻抗变换用的。能否将FB2与T2元件替换为简单且好理解的、像前级那样的变压器阻抗变换形式(FT-43磁芯)?3、我们想仿造30MHz的测试电路,直接应用于...

Resolved! Question about Writeprotect (WP) for I2C EEPROM, eg M24M01E

For these EEPROMs there is a WP pin, which must be (active) low to enable write operations. I am driving this pin from an MCU, (ie. it is not tied to GND).Also these EEPROMs need some time after a write command to effectively write the data into the ...
