    > Rugged Mobile RF PAs 10-25W
  • Technical requirements analysis
  • Complete TX chain specification, design and implementation
  • Integration of PA and TX into radio solution (software, mechanical, power supply)
  • PA ruggedness design
  • Component specification and sourcing
  • Block, subsystem and product integration testing
  • Resolution of design and integration issues
  • Type approval support
  • Support design, testing and troubleshooting in other areas of the product as appropriate
  • Technical support to end customers and subcontract manufactures
  • Progress reporting
