Abstract: A system module with a power device is provided to avoid deterioration of a power device and other devices by effectively radiating the heat generated from a power device through a radiation via in a main board and an unevenness on the lower surface of the main board. A power device package(112) is mounted on a main board(101). At least one radiation via is formed in the mounting region of the power device package in the main board, extended downwardly from the upper surface of the main board. An unevenness(102) is formed in the lower surface of the main board in a region where the radiation via is formed. The unevenness can be formed on a ground surface(104) on the lower surface of the main board.

Abstract: An RF(Radio Frequency) complex module having an improved harmonic suppressing function is provided to pass transmission signals toward an antenna on an output end, and to effectively suppress harmonic components of the transmission signals, thereby preventing harmonics of the transmission signals from being emitted through the antenna. A transmission signal processor(100) power-amplifies and filters the first to nth transmission signals corresponding to each of multiple bands. A switch(200) selects transmission signals corresponding to previously selected bands among the first to nth transmission signals. A variable filter(300) variably sets passing bands according to tuning voltages, and passes the selected transmission signals to the passing bands to output the passed signals, then removes harmonics of the transmission signals.

Abstract: PURPOSE: A TDD(Time Division Duplex)-type amplification module is provided to minimize the power consumption by executing an amplification operation in a TDD method so that power can be consumed as needed only. CONSTITUTION: Rx/Tx signals are inputted and outputted through the first and second ports(P1,P2). The first transmission line(L1), of which one end is connected to the first port(P1) through the first capacitor(C1), has a length of 1/4 for the wavelength of the Rx/Tx signals. The second transmission line(L2), of which one end is connected to the other end of the first transmission line(L1) and of which the other end is connected to the second port(P2) through the fifth capacitor(C5), has a length of 1/4 for the wavelength of the Rx/Tx signals. The cathode of the first pin diode(D1) is connected to the first port(P1) through the first capacitor(C1). The cathode of the second pin diode(D2) is connected to the second port(P2) through the fifth capacitor(C5). A matching network(41), connected to the anode of the first pin diode(D1) through the second capacitor(C2), executes impedance matching. A power amplifier(42), operated according to an inputted TDD control signal, amplifies a TX signal inputted through the matching network(41).
