Abstract
The present invention is a high power direct transmitter with frequency-shift keying (FSK) modulation. The transmitter implements a high power, high efficiency power voltage-controlled oscillator (VCO) which allows for production of a modulated RF signal at the final stage (ex.—right at the antenna), thereby eliminating all driving stage power amplification and frequency translation. The transmitter further provides a low SWAP-C alternative to currently available solutions.
