“World's first” 50V LDMOS power transistors for L-Band radar applications

Freescale Semiconductor has unveiled the first 50-volt LDMOS RF power transistor line-up for L-Band radar applications. Ideal for a wide range of high-power RF applications including air traffic management and long-range weather radar, the RF product line includes the MRF6V14300H final stage device and the MRF6V10010N driver.

The advanced line of RF power transistors - the first in Freescale's 50 V RF power LDMOS avionics and radar portfolio - provides competitive advantages, such as a standard voltage supply, low cooling costs and high reliability of pallet design for Freescale's customers designing pulsed RF power opportunities in L-Band frequencies.

The thermal resistance of Freescale's MRF6V14300H device, packaged in a RoHS compliant, air-cavity ceramic package, is less than 0.12o C/W JC, which is engineered to effectively manage heat dissipation and reduce heat sink size. The excellent thermal performance provides cooler junction temperature. The MRF6V10010N is in an over-molded plastic package, also offering significant thermal performance. When combined in a line-up, the result is low cooling costs and high reliability of a pallet design.

Like other devices in Freescale's 50 V LDMOS family, these advanced devices incorporate electrostatic-discharge (ESD) protection to help reduce their susceptibility to electrostatic events on assembly sites. This ESD protection enables a wide gate voltage swing capability of -6 V and +10 V, which is advantageous when the devices are operating in higher efficiency classes such as Class C.
