en- NXP's LDMOS RF power transistors come in standard TO-247 and TO-220 packages

NXP Semiconductors offers two power blocks that promise to expand the RF power industry and become a standard for years to come. The simplicity of these LDMOS transistors lies in the joint availability of RF power in ubiquitous TO-247 and TO-220 power packages, making mounting easy.

The TO-247 and TO-220 packages make it possible to mount RF power transistors with a simple through-hole technology, removing the need for a complex solder-reflow process which dramatically simplifies manufacturing. The compact reference circuits can be re-used from 1.8 MHz to 250 MHz resulting in considerable savings and simplified supply chain for most HF and VHF systems.

Features
PA design reuse over frequencies The MRF300AN is supported by a series of narrowband reference circuits that share the same PCB layout (2" x 3” or 5.1 cm x 7.1 cm), enabling RF designers to generate power amplifiers to address other frequencies quickly Two pin-configurations enabling wideband designs Both 100 W and 300 W solutions come in 2 pin-out versions mirroring each other to support push-pull configurations		Low-cost and flexible mounting Many mounting options provide a great flexibility that helps further reduce the BoM and time-to-market The TO-247 and TO-220 ubiquitous packages make it possible to mount RF power transistors with a simple through-hole technology, removing the need for a complex solder-reflow process, dramatically improving the usability in manufacturing
