Claims (1)

[Claims for Utility Model Registration] (1) In a converter that is supplied with power from an external source and converts a received signal to a predetermined frequency and outputs the converted signal, an electronic cooling device that cools a semiconductor element that amplifies the received signal; 1. A low-noise converter comprising: power supply means that uses the difference between the power supplied from the electronic cooling device and the power consumed internally as a power source for the electronic cooling device. (2) In a converter that is supplied with power from the outside and converts the received signal to a predetermined frequency and outputs it, there is an electronic cooling device that cools the semiconductor element that amplifies the received signal, and a power supply that is supplied from the outside and the inside. 1. A low-noise converter comprising: a power supply means for supplying power to the electronic cooling device using the difference in power from the power consumed by the electronic cooling device; and a sealing means for sealing the semiconductor element.
