2-watt PA power amplifier for Morning-core CX660x TDD transmission transceiver module
Table of Contents
Optional Frequency Watts
- 2-watt, 5-watt, 10-watts
- Frequency 800Mhz, 1400Mhz(1.4G) and 2400Mhz (2.4G)
Introduction
- The CX6603 transmission power of the Morning-Core video transmission transceiver module is 0.3 watts only, So the transmission range is limited
- Please increase this 2-watt PA power amplifier, you can increase transmission power and extend the transmission distance and range to 30-50km.
Feature
- The transceiver is integrated on the same circuit board in TDD mode. An analog switch chip separates the internal RF transceiver and transceiver signals, while the external RF interface is merely one SMA interface.
- The 2W power amplifier module link design, which includes a power amplifier tube and an LNA, can be paired with the CX660x baseband board design.
- Receive gain 13dB, transmit gain 15dB, output power 33 dBm.
- A separate power amplifier box is required for the structural design of a 2W power amplifier module; the whole product also requires the external design of the entire shell, power supply, control signal input, RF connection, antenna interface, power amplifier heat dissipation, and so on.
- The design of the 2W power amplifier module only considers function realization, and the functions of power amplifier working status, performance indicators, alarm information, and temperature characteristic compensation are not realized, which is not conducive to the indicators and quality control of power amplifier module production and testing, as well as the response and processing of abnormal problems in field application.

FAQ
Question: Does this TDD PA power amplifier work well with my MorningCore CX6600 module?
There are no switches (SCL) on the pin of the i2c CLK on my CX6600 module.
Answer: The engineer said that if there is no pa control line, this version is the cheapest version and additional pa can not be added. Because your module is not our solution, you’d better consult your supplier. Our modules can be equipped with control lines and additional pa. If you are interested, you can buy a 1681 sample from us to test.
The engineer said you can use the AT command to query the version number and send it to see if it supports external PA AT^DGMA? Or query the firmware version information in the web UI and send it to me.
How to check the core communication module version number of the drone video data link?
Question: Here is the checking hardware version information result.
^DGMR:”CX6602N V2.00.00 R3 20230731
OK
Answer: Your module is CX6602N, which does not support external PA.
