摩托罗拉半导体部最近宣布研制成功最新LDMOS RF功率晶体管,与用双极制造的器件相比具有更大的线性度。现已生产的型号有MRF184和MRF184S,它的最大特点是高增益和宽带性能。这些性能使它非常适用于28V基站设备中的大信号共用源电路中。 新款晶体管主要设计目的是用于宽带商业和工业应用方案中,能用在100到1000MHz宽带应用范围内。这些新款器件由于具有卓越的固态放大器性能,能提供优良的线性度、高效率、高增益和良好的热阻特性的大功率输出。
Motorola Semiconductor recently announced the successful development of its latest LDMOS RF power transistor, which offers greater linearity than bipolar devices. Now produced models MRF184 and MRF184S, its most prominent feature is the high gain and broadband performance. These properties make it ideal for large-signal common-source circuits in 28V base station equipment. The new transistor is primarily designed for use in broadband commercial and industrial applications and can be used in broadband applications from 100 to 1000 MHz. These new devices offer high power output with excellent linearity, high efficiency, high gain, and good thermal resistance due to their superior solid-state amplifier performance.
