Freescale Semiconductor has introduced a new 6 W LDMOS Transistor for handheld mobile radio applications called the AFT05MS006N. With this addition to its Airfast RF power solutions portfolio, Freescale can now support all power levels of relevance to the mobile radio space, from 5 W handheld units to 75 W digital mobile radios and base stations.
The 6W AFT05MS006N integrates circuitry to increase stability, thereby simplifying design and supporting a wide range of operating conditions. In addition, the new device is extremely rugged, enabling optimal performance even in harsh operating conditions such as public safety, professional mobile radio and machine-to-machine communications environments. This transistor has been targeted for handheld mobile radio applications, however can be used as a driver in higher powered mobile radio solutions as well.
The transistor has a VSWR > 65:1, even with simultaneous overvoltage and overdrive stressing the amplifier and its RF power transistors. Additionally, the efficiency of the Airfast devices is on average 65 percent, an improvement when compared to module-based solutions, which typically range from 25 to 40 percent in efficiency.
Freescale also recently released to production the previously announced AFT09MS015N, which is a 15 W LDMOS transistor with a high gain, extreme ruggedness and wide bandwidth capability. It is ideal for 10W mobile radio designs.
