KH658 L/S/B3, BeiDou external antenna all-in-one module

1. Overview
KH658 is a BeiDou external antenna all-in-one module, consisting of an active external antenna and an RF cable. The RF cable enables bidirectional transmission of RF signals and power supply. When used with a BeiDou terminal, it supports short message communication, position reporting, and navigation functions.

The module integrates high-precision antennas for L-band, S-band, and B3 frequencies, making it suitable for high-accuracy outdoor positioning and navigation applications. It also features a built-in low-noise amplifier (LNA) module and filtering circuits to suppress interference signals, ensuring stable operation even in harsh electromagnetic environments.


2. Key Functions

  1. Equipped with a built-in high-precision antenna. The received B3 and S-band signals are amplified, filtered, and combined through the integrated LNA and filters before output.

  2. Built-in power detection function. When the input power at the L-band exceeds a certain threshold, the power amplifier is automatically activated.

  3. Integrated 5W power amplifier, which amplifies and filters the L-band transmission signal before output.
