Abstract:
1. A magnetic resonance imaging (MRI) Balanced Mixer apparatus comprising: an RF coil; a preamplifier module comprising: a transmission line; a hub coupled to the preamplifier module via the transmission line; an intermediate frequency (IF) circuit coupled to the transmission line; and an oscillator circuit coupled to the hub and configured to supply an oscillating signal to the diode array via the transmission line in order to cause the diode array to mix the oscillating signal with the first signal and configured to generate an IF signal to be received by the IF circuit via the transmission line, wherein the IF signal has a second frequency that is lower than the first frequency; wherein the transmission line connects each of the preamplifier module, the hub, the IF circuit and the oscillator circuit together.
