Warranty：If you are not satisfied within 15 days, you can return or exchange the goods
1) OVERHEAT PROTECTION:
The transmitter will switch to auto-protection with alarm message and a beep sound once the working temperature gets higher than normal range.
2) OVER SWR PROTECTION:
SWR is the indication of antenna system connection with transmitter. Once the connection is bad and causing a high SWR Value, the transmitter will switch to automatic protection mode by showing alarm message on the screen with a beeping sound meanwhile.
3) FAN ERROR ALARM
When the fan stops running, the alarm message will be displayed on the screen
4) ADJUSTABLE POWER OUTPUT
The RF out of this 500w FM transmitter is continuously adjustable from 0-500 watt at the stepping of 0.1watt, which means you can tune it to 1w...1.1w...1.2w...50w...100w...300w...350w...500w, with just one transmitter you’ll get multiple modes of outputs and easy to tune as per your needs
The transmitter implements digital FM modulator module as its core,combining with RF power amplifier.In the transmitter,DSP&DDS are used to execute all-digital processing,such as digital filtering,pre-emphasis,the generation of pilot frequency,stereo coding and FM modulating.A AGC circuit is used to keep the set power stable.
High performance and very good reliability has been proved by the large usage of YXHT-500W transmitters.Also it is low cost and small size.
RF amplifier uses NXP LDMOS transistor BLF188XR, making it able to withstand severe load mismatch of more than 65: 1 VSWR at 5dB compression point.
FREQUENTLY APPLICABLE USES:
