Radio frequency module for antenna, radio frequency module assembly and antenna device comprising same

The present invention relates to a radio frequency (RF) module for an antenna, a radio frequency module assembly and an antenna device comprising the same, and more particularly, to a radio frequency (RF) module for an antenna, comprising: a radio frequency filter formed with at least four outer side surfaces; a radiating element module disposed on one of the outer side surfaces of the radio frequency filter; an amplification part substrate which is arranged on the other surface of the outer side surfaces of the radio frequency filter and on which an analog amplification element is sealed; and a reflector which is disposed between the radio frequency filter and the radiating element module so that the radiating element module is grounded (GND), and which dissipates heat generated by the radio frequency filter to the outside, in which the radio frequency module for an antenna is inserted into a main board disposed on an antenna housing per module unit. Thus, there is no need to provide a radome that hinders he
