IPC分类:

H	电学
H03	基本电子电路
H03D	由一个载频到另一载频对调制进行解调或变换（微波激射器、激光器入H01S；调制器和解调器都可应用的电路入H03C，例如平衡调制器H03C1/54；调制器和变频器都可应用的零部件入H03C；脉冲解调入H03K9/00；经连续变量信号调制的脉冲调制形式的变换入H03K11/00；；中继系统，例如中继站入H04B7/14；用于数字调制载波系统的解调器入H04L27/00；用于彩色电视的同步解调器入H04N9/66）
H03D7/00	从一个载频到另一载频调制的变换，例如频率变换（H03D9/00，H03D11/00优先；用作变频器的介质放大器、磁放大器、参量放大器入H03F）
H03D7/02	.采用二极管（H03D7/14至H03D7/22优先）
