A ROBUST DIGITAL WIRELESS LINK FOR TACTICAL UAV’S

ITC/USA 2005 Conference Proceedings / The Forty-First Annual International Telemetering Conference and Technical Exhibition / October 24-27, 2005 / Riviera Hotel & Convention Center, Las Vegas, Nevada / A conventionally designed radio frequency amplifier operated in its linear region exhibits
low DC to RF conversion efficiency. Typically, for a power amplifier designed for digital
modulation applications, the amplifier is operated “backed-off” from its P1dB point by a factor of 10
or -10 dB. The typical linear amplifier is biased for either Class A or Class A/B operation
depending on the acceptable design trade-offs between efficiency and linearity between these two
methods. A novel design approach to increasing the efficiency of a linear RF power amplifier using
a modified Odd-Way Doherty technique is presented in this paper. The design was simulated, built
and then tested. The design yields improvements in efficiency and linearity.
