The Gamma Series achieves 80% efficiency with LDMOS based amplifiers. This results in a low cost of ownership. There is also additional cost savings resulting from the lower heat generation of these amplifiers. Less power is lost to generated heat and thus less power is required by HVAC systems to cool the transmitter building. The electric power savings in this new PTEK design is significant.
