Various embodiments provide for systems and methods for signal conversion of one modulated signal to another modulated signal using demodulation and then re-modulation. According to some embodiments, a signal receiving system may comprise an I/Q demodulator that demodulates a first modulated signal to an in-phase ('I') signal and a quadrature ('Q') signal, an I/Q signal adjustor that adaptively adjusts the Q signal to increase the signal-to-noise ratio (SNR) of a transitory signal that is based on a second modulated signal, and an I/Q modulator that modulates the I signal and the adjusted Q signal to the second modulated signal. To increase the SNR, the Q signal may be adjusted based on a calculated error determined for the transitory signal during demodulation by a demodulator downstream from the I/Q modulator.

Power measurement and control in transmission systems are affected by changes in load conditions. A method and system are provided for detecting and controlling power levels independent of such load conditions.

A power divider includes an input port, a first output port, a second output port, a first transformer coupled between the input port and the first output port, and a second transformer coupled between the input port and the second output port. The first and second transformers each incorporates a low pass filter. The power divider further includes a ground plate disposed adjacent to the first and second transformers. The ground plate is capacitively coupled to the low pass filters of the first and second transformers for enhancing the low pass filtering characteristics of the power divider. The power divider provides low pass filtering capability while achieving a significant size reduction over conventional power dividers.
