タ。 In a microwave converter, the received microwave is amplified by a low-noise amplifier circuit and then mixed with the output oscillation signal of an oscillation circuit to perform low-frequency conversion. All of the circuits that perform this are arranged on substantially one surface of a board attached to the bottom of the case, and the low-noise amplifier circuit is electromagnetically separated from the circuit that performs low-frequency conversion by the oscillation circuit and mixing circuit. A microwave converter comprising an isolation wall provided inside the case.
