Abstract

Heatsink performance in two way radios has continued to become more critical as product size decreases and performance requirements increase. Typically, very expensive heatsink fabrication methods or changes to alternate cooling technolo- gies have been required in order to provide the needed thermal performance. Preferred, low cost technologies include free and forced convection using a die cast or extruded heatsink. Expensive technologies include bonded fin heatsinks, heat pipes, closed refrigeration systems, air conditioning, etc.
