1. Overview

The LTD-BH1000 is a personal mobile communication device that incorporates
the latest compact radio technology, including smaller and lighter components
and support for WCDMA(850/1900MHz) bands. This device acts as the
vehicle’s telematics system and connects to WCDMA (HSPA+) wireless
networks and wireless modules to allow voice and data communication.
Furthermore, this device can operate on land and water as well as other similar
areas.
In HSPA+ mode, the device provides uplink speeds of up to 5.76 Mbps and
downlink speeds of up to 14.4 Mbps for seamless transfer of data such as
movies and video calls. The device also supports the transfer of large amounts
of data.
The device communicates with the host system via a standard RS-232 or USB
port, and AT commands and control commands can be used to send data. Voice
calls are also possible.

4. Electrical specifications

4.1 Power supply specifications

The host system provides the power supply (V_BATT)DC 4 V, 1.5 A to the
device. The internal power supply module manages the power supplied to the
integral circuits and maintains constant voltages. This module also controls
each power block to minimize power consumption.

In particular, the PAM (power amplifier module) consumes a lot of power, so it

receives a direct power supply of 4 V from the V_BATT. Therefore the
V_BATT signal inputs only the supply power of the PAM, even when the
absolute rating is higher. In addition, the entire power input module blocks and
protects against high surges and ESD in the NAD module.
