Abstract: Disclosed is a multi-band transmitter for transmitting a multi-band signal. The multi-band transmitter comprises: a pre-distortion unit including a first digital pre-distorter (DPD) which pre-distorts a first band signal and a second DPD which pre-distorts a second band signal discontinuous from the first band signal; a conversion unit which analog-converts the pre-distorted first band signal and the pre-distorted second band signal; an amplification unit including a first power amplifier (PA), which amplifies the analog-converted first band signal, and a second PA, which amplifies the analog-converted second band signal; and a feedback unit which digital-converts the amplified first band signal to feed the digital-converted first band signal back to the first DPD and digital-converts the amplified second band signal to feed the digital-converted second band signal back to the second DPD. The pre-distortion unit performs pre-distortion by using the fed-back first band signal and the fed-back second band signal.

Abstract: The present disclosure relates to an antenna RF module, an RF module assembly including the antenna RF modules, and an antenna apparatus including the RF module assembly. The antenna RF module includes an RF filter arranged on a front surface of a main board, a radiation element module arranged on a first side of the RF filter, and a reflector arranged between the RF filter and the radiation element module in such a manner as to ground (GND) the radiation element module and, at the same time, to serve as an intermediary for dissipating heat generated in the RF filter to the outside. Accordingly, a radome that interrupts dissipation of heat to in front of an antenna is unnecessary, and heat generated from heat generating elements of the antenna apparatus is spatially separated. Thus, it is possible that the heat is dissipated in a distributed manner toward the front and rear directions of the antenna apparatus. The advantage of greatly improving performance in heat dissipation can be achieved. Moreover, the advantage of improving the ease with which the antenna RF module is assembled can be achieved.
