NXP Semiconductors MRFX1K80射频功率LDMOS晶体管
NXP Semiconductors MRFX1K80射频功率LDMOS晶体管将高射频输出功率与卓越的坚固结构和热性能完美结合。MRFX1K80晶体管设计用于在65V CW（连续波）时提供1800W功率，适用于1MHz到470MHz的应用，并且能够处理65:1的电压驻波比(VSWR)。 MRFX1K80射频功率LDMOS晶体管可耐受较高电压，因此能够实现更高的输出功率，从而有助于减少采用的晶体管数量、简化功率放大器的复杂性并减小其尺寸。借助这种耐高压特性，还可降低系统中的电流，从而限制直流电源上的应力并减小磁辐射。 另外，MRFX1K80还与前一代NXP LDMOS晶体管引脚对引脚兼容，可让射频设计人员重复使用现有的印刷电路板(PCB)设计，以缩短产品上市时间。 MRFX1K80射频功率LDMOS晶体管有两种封装类型可供选择。MRFX1K80H采用NI-1230气腔型陶瓷封装，具有0.09ºC/W的低热阻。MRFX1K80N采用OM-1230超模压塑料封装，热阻通常会低30%。
The high voltage of the MRFX1K80 RF Power LDMOS Transistor enables higher output power, which helps decrease the number of transistors to combine, simplifying power amplifiers complexity and reducing their size. The high voltage also lowers the current in the system, limiting the stresses on DC power supplies and reducing magnetic radiation.
The MRFX1K80 is also pin-to-pin compatible with previous generation NXP LDMOS transistors, making it possible for RF designers to reuse existing printed circuit board (PCB) designs for a shorter time to market.
The MRFX1K80 RF Power LDMOS Transistor is offered in two package types. The MRFX1K80H is housed in a NI-1230 air cavity ceramic package, with a low thermal resistance of 0.09ºC/W. The MRFX1K80N is housed in an OM-1230 Over-Molded plastic package, and will typically offer a 30% lower thermal resistance.
