An electronic component module has a device-side module A and an antenna-side module B. By such a manner, the apparatus of the present invention is capable of providing suitable drive channel for different sized nails. In a development, a cascode circuit having an additional pair of bipolar transistors is provided, which makes it possible to achieve a higher linearity without increasing the supply voltage. The resultant blend of hydrocarbons which has a sulfur content of at least 1 ppm, is fed to a naphtha cracking unit and ethylene recovered.
