2-watt PA power amplifier for Morning-core CX660x TDD transmission transceiver module.

2-watt PA power amplifier for Morning-core CX660x TDD transmission transceiver module.

sissejuhatus

1. The CX6603 transmission power of the Morning-Core video transmission transceiver module is 0.3 watts only, So the transmission range is limited
2. Please increase this 2-watt PA power amplifier, you can increase transmission power and extend the transmission distance and range to 30-50km.

tunnusjoon

1. 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.
2. 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.
3. Receive gain 13dB, transmit gain 15dB, output power 33 dBm.
4. 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, toiteallikas, control signal input, RF connection, antenna interface, power amplifier heat dissipation, ja nii edasi.
5. 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.
