Embodiment Construction

[0016] The present invention provides a device for transmitting and receiving selector switch and antenna selector switch, so as to solve the problem of how to improve the receiving sensitivity and improve the quality, coverage and capacity of the network. Specific embodiments are described in detail below, but not as a limitation to the present invention.

[0017] The present invention is mainly aimed at the two-antenna system, and can be extended correspondingly for the multi-antenna system.

[0018] in such as figure 2 In the shown, 201, 202 are antenna 1 and antenna 2, 204 is an antenna selection switch, 205 is a transceiver selection switch, 206 is a transmitting channel amplifier, 207 is a receiving channel low noise amplifier, and 203 is composed of ANTSEL and / or ANTSEL antenna selection switch and RXPAON and / RXPAON transceiver switch combined device. Both the antenna selection switch 204 and the transceiver selection switch 205 include a common terminal and two spl...

Abstract

The invention discloses a transceiver selection switch and antenna selection switch device, which is used in two- antenna system, the device comprises: two antennas, antenna selection switch, transceivers selection switch, fired channel amplifier, receiver channel low noise amplifier, and antenna selection switch / transceiver selection switch control signal combiner; wherein two antennas are connected separately with the combination of method to combiner through the antenna selection switch and the transceivers selection switch, the fired channel amplifier connected with the antenna selection switch sends signals, the receiver channel low noise amplifier connected with transceiver selection switch receives signals, the combiner according to received different control signals in two antenna system, produces two control signals to the antenna selection switch and transceivers selection switch, and executes sending signals and receiving signals operation through two antennas. The invention achieves the objective of improving the receiver sensitivity, improves the network quality, coverage and capacity, and other issues.

Description

technical field [0001] The present invention relates to a transmission and reception selection switch and an antenna selection switch device in a system for antenna diversity transmission diversity reception under the time-division working state in the field of wireless communication systems. Transceiver selection switch and antenna selection switch device in the system. Background technique [0002] In a time-division communication system, it is necessary to select transceivers. At the same time, in order to improve communication quality, diversity transmission and diversity reception are required. Two antennas receive air signals at the same time. The baseband board detects, calculates and processes the RSSI (Received Signal Strength Indicator (received signal strength indication) signal, to determine the signal quality received by the current antenna, thereby giving a control signal for antenna selection, and the antenna selection module completes the function of antenna ...
