摘要： A high frequency wireless circuit apparatus is formed by connecting a phase shifter between an antenna duplexer and a low noise amplifier, so that the impedance of the receiving terminal of the antenna duplexer at a transmission frequency and the input impedance of the low noise amplifier may not be matched in complex conjugates of each other. Therefore it prevents the transmission output passing through the receiving terminal of the antenna duplexer and the interference signal entered through the antenna from making the cross modulation in the low noise amplifier. Thus it improves the reception sensitivity and immunity to interference signals of the high frequency wireless circuit apparatus at the same time.

摘要： A method of producing a phenol compound comprising a step of oxidizing an aromatic aldehyde to an aryl formate and an aromatic carboxylic acid with an oxygen-containing gas, and a step of decomposing the aryl formate to the phenol compound. To facilitate the separation of the aryl formate and the unreacted aromatic aldehyde, a mixture of the aryl formate and the unreacted aromatic aldehyde is recycled to the oxidation process to concentrate the aryl formate in the oxidation mixture. Alternatively, the oxidation process is carried out in an organic solvent having substantially no ability of dissolving water to increase the conversion of the aromatic aldehyde and the selectivity of the aryl formate, thereby producing the aryl formate in a high yield. In another method, the aryl formate is produced by oxidizing the aromatic aldehyde in the organic solvent having substantially no ability of dissolving water with performic acid generated in situ in the reaction system from the reaction between formic acid and hydrogen peroxide. Since the oxidation proceeds in the organic solvent, hydrogen peroxide in aqueous phase contact the aromatic aldehyde. This significantly reduces the amount of explosive cyclic perther and a high-boiling product.
