Abstract
In a frequency conversion apparatus, a first frequency conversion section is disposed in a first accommodating site, a second frequency conversion section is disposed in a second accommodating site, two shield plates are interposed between the first accommodating site and the second accommodating site, a first partitioned chamber is formed in the region surrounded by the shield plates, a first power supply line is disposed in the first partitioned chamber. Power is directly supplied from the first power supply line to the first frequency conversion section and the second frequency conversion section. With this arrangement, interference caused by the existence of two local oscillators is reduced without increasing the size of metal cases.
