Abstract
A radio frequency module includes a multi-chip substrate divided into separate substrates. An antenna block, a duplexer block, a transmitter block, a receiver block, and an oscillator block are formed on the separate substrates. Connection resonators, which are connected to transmission lines, are formed at edges of the separate substrates. The connection resonators on adjacent ones of the separate substrates are arranged close to each other such that the two adjacent resonators are electromagnetically coupled to each other. Thus, the transmission lines on the separate substrates are interconnected, and a signal can be propagated among the blocks.
