Freescale Semiconductor has released a 50-volt LDMOS RF power transistor line-up for L-Band radar applications. The line-up is intended for a variety 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 MRF6V14300H produces pulsed RF output power of 330W at frequencies between 1200MHz and 1400MHz. The thermal resistance of Freescale’s MRF6V14300H device, packaged in a RoHS compliant, air-cavity ceramic package, is less than 0.12o C/W qJC, which is engineered to manage heat dissipation and reduce heat sink size. The MRF6V10010N is in an over-molded plastic package, also offering thermal performance.
