Problems solved by technology

[0003] The existing repeater packs each component in the shell, and the isolation of the built-in antenna is poor, which affects the product performance and is bulky; in addition, the existing shell is a rectangular box, and only the heat dissipation holes are opened on the back plate, so that The heat generated when the repeater is working has been accumulated inside for a long time, and it can only be dissipated slowly through the cooling holes on the backplane in a static heat dissipation method. device lifetime

Abstract

A radio frequency repeater device comprises an outer shell and a repeater module which is installed in the outer shell, wherein the repeater module comprises a first antenna, a first supporting cover, a first shielding cover, a circuit board, a second shielding cover, a second supporting cover and a second antenna; the first shielding cover is installed on a first panel of the circuit board, and the second shielding cover is installed on a second panel of the circuit board; a backboard of the first supporting cover is installed on a backboard of the first shielding cover, and a backboard of the second supporting cover is installed on a backboard of the second shielding cover; and the first antenna is arranged inside the first supporting cover, and the second antenna is arranged inside the second supporting cover. According to the radio frequency repeater device, an effective isolation mechanism is formed by the first supporting cover, the first shielding cover, the second shielding cover and the second supporting cover, the isolation between the first antenna and the second antenna is greatly improved, the radio frequency anti-interference capability of the repeater device is optimized, and the repeater module is compact in structure and small in size.

Description

technical field [0001] The invention relates to a radio frequency repeater device. Background technique [0002] The repeater is an uplink and downlink amplification link composed of antennas, radio frequency duplexers, low noise amplifiers, mixers, electronically adjustable attenuators, filters, power amplifiers and other components. The basic principle of its work is: use the forward antenna (donor antenna) to receive the downlink signal of the base station into the repeater, amplify the useful signal through the low-noise amplifier, suppress the noise signal in the signal, and improve the signal-to-noise ratio (S / N ); then down-converted to an intermediate frequency signal, filtered by a filter, amplified by an intermediate frequency, and then frequency-shifted and up-converted to a radio frequency, amplified by a power amplifier, and transmitted to the mobile station by the backward antenna (retransmitting antenna); at the same time, the backward antenna is used The upl...
