摘要
A higher frequency modulator built with low cost materials and with a lower power requirement is described as well as methods relating thereto. A received radio frequency (RF) signal is combined with a created local oscillator (LO) signal to result in a combined radio frequency (RF) signal, which may be converted into a message signal. A subharmonic mixer may be used to convert the combined RF signal into the message signal. The subharmonic mixer may include antiparallel diode pair (APDP) topology. The created LO signal is a combination of a selected LO signal with another LO signal. The selected LO signal may be a subharmonic of the RF signal. The other LO signal may be a low odd-order harmonic of the selected LO signal. Preferably, the created LO signal is not greater than the RF signal.
