Embodiment Construction

[0043] attached figure 1 A switching module is shown with a switch 1 having an output 4 as well as two transmitter inputs 2 and three receiver inputs 3 . In addition, the switch module has two low-pass filters 5, 6, wherein the low-pass filter 5 can be designed for the GSM frequency band, and the low-pass filter 6 can be Designed for PCN / PCS bands. Said switch 1 selectively connects one of the input terminals 2, 3 to the output terminal 4 of the switch. Furthermore, the switch 1 described has bandpass filters 10 , 11 , 12 which are connected to the receiver input 3 . The band-pass filter 10 matches the GSM frequency, the band-pass filter 11 matches the PCN frequency, and the band-pass filter 12 matches the PCS frequency. The bandpass filters 10 , 11 , 12 can be arranged either as separate components on the upper or lower side of the base body or, however, can also be formed from passive components integrated into a passive module.

Abstract

The module has a voltage-controlled switch with transmitter and receiver inputs and an output and selectively connects one input to the output. It has passive components forming a low pass filter connected to a transmitter input of the switch. The passive components are constituents of a multilayer ceramic passive module with a base body of stacked dielectric and electrically conducting layers. The switch is on the upper or lower side of the body. The module has a voltage-controlled switch (1) with transmitter and receiver inputs (2,3) and an output (4) and selectively connects one of the inputs to the output. It has passive components forming a low pass filter (5,6) electrically connected to a transmitter input of the switch. The passive components are constituents of a multilayer ceramic passive module with a base body of stacked dielectric and electrically conducting layers. The switch is mounted on the upper or lower side of the base body. Independent claims are also included for the following: the use of an inventive circuit module as the front-end module in a mobile radio device.

Description

technical field [0001] The invention relates to an electrical switch module with a switch and with passive components forming a low-pass filter, the switch has a transmitter input and a receiver input and an output, and the switch Optionally one of the inputs is conductively connected to the output, and the low-pass filter is conductively connected to the transmitter input of the switch. Background technique [0002] Switching modules of the above-mentioned type are known, in which the switches consist of PIN diodes and are therefore current-controlled. At this time, a low-pass filter integrated into an LTCC multilayer ceramic having 10 to 15 ceramic layers is employed. These switching modules are used as multiband front-end modules for mobile telephones and each have a receiver input and a transmitter input for at least two different frequency bands. [0003] Such known switch modules perform the following different functions: [0004] Function 1: Logical connection of t...
