In the present embodiment, radio frequency control module 130 adopts control relay circuit, as shown in Figure 7, comprise transistor Q1, relay R elay1 and multiple resistance, radio-frequency (RF) control signal accesses to the base stage of transistor Q1 by resistance, the emitter of transistor Q1, by grounding through resistance, is connected by resistance between collector electrode with relay R elay1.When PA_Ctrl output logic high level, transistor Q1 conducting, makes relay R elay1 be energized, then the contact of relay R elay1 disconnects, and the radio frequency amplifier of radio-frequency module 210 will lose power supply supply and quit work.And the radio frequency amplifier of radio-frequency module 210 is when normally working, relay R elay1 contact is in normally off.
In addition, under normal circumstances, only include a radio frequency amplifier in radio-frequency module 210, radio frequency control module 130 so of the present invention controls the opening and closing of the radio frequency amplifier of radio-frequency module 210.But, in some special case situations, radio-frequency module 210 may comprise multiple radio frequency amplifier, so, radio frequency control module 130 in the present invention is also multiple, and quantity is consistent with the quantity of the radio frequency amplifier of radio-frequency module 210, radio frequency control module 130 and the radio frequency amplifier one_to_one corresponding in radio-frequency module 210.The circuit of each radio frequency control module 130 all as shown in Figure 7, is not described in detail in this.
