Abstract

The invention discloses a single-chip radio frequency antenna switch module. The single-chip radio frequency antenna switch module comprises a substrate, a die, a first low pass filter and a second low pass filter. The inductance of the first low pass filter and the inductance of the second low pass filter are achieved through a metal wire and/or a bonding wire on the substrate. The die is installed on the substrate, and a radio frequency antenna switch, a logic controller, a capacitor of the first low pass filter and a capacitor of the second low pass filter are integrated into the die, and the logic controller is used for turning on or turning off the radio frequency antenna switch according to logic signals. The implementation way is easy to implement, the area of the substrate of the radio frequency antenna switch module can be fully utilized, and therefore the size of the radio frequency antenna switch module can be reduced, and the cost of the radio frequency antenna switch module can be lowered.

Description

Technical field [0001] The invention relates to the technical field of integrated circuits, in particular to a single-chip radio frequency antenna switch module and radio frequency front end. Background technique [0002] With the development of mobile communication technology, five mobile communication modes coexist, such as GSM / EGDE, WCDMA, TD-CDMA, FDD-LTE and TD-LTE, etc. Multi-mode technology effectively integrates these mobile communication modes into the same multi-mode handheld terminal, so that the same handheld terminal is compatible with the aforementioned communication modes at the same time. Due to the different frequency bands of the above communication modes, the radio frequency antenna switch must cover all the operating frequencies of the above modes. [0003] A typical multi-mode RF antenna switch module such as figure 1 Shown. by figure 1 It can be seen that the multi-mode RF antenna switch module 101 is a single-pole twelve-throw RF switch. Its single-pole RF ...
