Why LDMOS technology ?

Ultra reliable LDMOS technology has 20 years of proven widespread use in extremely high SWR environments -- commercial broadcast transmitter and industrial applications like plasma generators, lasers and MRIs. The LDMOS transistor used in ALS-706 is designed to handle SWR up to 65:1. It can withstand almost any load from a short to an open circuit!!!.

Benefits of LDMOS transistor used in the ALS-706:
  •  Very good linearity--gives you clean SSB, CW and digital signals
  • Superior efficiency-- gives you more power output for less power consumed
  • No catastrophic overheating because of thermal runaway--protects against sudden transistor failure
  • Excellent structural thermal conductivity--readily channels unwanted heat out and allows significantly higher continuous RF power level
