The UTV 005 is a COMMON EMITTER transistor capable of providing 0.5 Watt Peak, Class A, RF Output Power over the band 470 - 860 MHz. Gold Metalization and Diffused Ballasting are used to provide high reliability and supreme ruggedness
机翻:
UTV 005 是一种通用发射极晶体管,能够在 470 - 860 MHz 频段内提供 0.5 瓦峰值、A 类射频输出功率。 金金属化和扩散镇流用于提供高可靠性和最高的耐用性
所以是个电源控制器?
