Built-in high-quality professional stereo encoder.
Excellent power AGC balance control system, the power output can be adjusted from 0 to full power, and has automatic gain power control to maintain the output power within a set range without drifting.
Support external input modulation RDS or SCA signal.
Supports AES-EBU digital signal input, 24Bit 192KHz sampling rate input range, true lossless audio (Default digital signal priority).
Can be used for FM (same frequency synchronization) broadcasting system. Provide options for synchronization 10MHz standard frequency input or built-in GPS module according to customer requirements
Equipped with RS232 communication interface, users can control all operations through the transmitter communication protocol.
The RF power amplifier part is synthesized by using multiple modules, and the amplification module uses NXP LDMOS transistor BLF188XR. It is able to withstand severe load mismatch of more than 65: 1 VSWR at 5dB compression point. Using superconducting welding technology, the transistor is welded on the copper plate to obtain excellent thermal conductivity and the power amplifier transistor has never been damaged so far.
All circuits adopt the design of split modules, and each modules have status indicators to check its working performance, which reduces maintenance and replacement costs.
Innovative RF module status monitoring and fault notification. If a module fails, you only need to replace the module with specified number according to the system prompt.
Automatically record 9 latest device alarms for later troubleshooting.
