<p>A composite high-frequency component has a diplexer (102) for separating/combining transmission/reception signals in frequency bands of a plurality of communication systems, transmit/receive switches (103) (104), filters (105) (106), and a balanced-unbalanced reception signal switch (124), and a matching circuit (108). The balanced-unbalanced reception signal switch (124) is composed of a reception signal switch (121) and balanced-unbalanced filters (122) (123). A stripline (GSL2) in the transmit/receive switch (103) and a stripline (ASL2) in the reception signal switch (121) are formed on the same layers, and the matching circuit (108) composed of capacitors (GCu3) (AGPr) is arranged between the transmit/receive switch (103) and the reception signal switch (121).</p> |
