Product Category:Products > FM stereo transmitters
Brief introduction:
  • Details Introduction

1.        Exciter is TF(S)-30D. Driver is 500W.

2.        16*500W wide band amplifier cards, equipped with Philips BLF177 Mosfet transistors, assure the highest redundancy. No adjustment are required for the full power operation in the 87 ~ 108 MHz.

3.        Superior harmonic radiation (<-70dB, typical –75dB). Low pass filters are adapted to reduce receiving interference.

4.        Amplifier cards are designed as assembly block. 4*500W is made up one block and put in 19” standard rack. Maintenance possible with little qualified personnel.

5.        Full protection functions, such as over temperature, over voltage, over current, VSWR etc. The transmitter will continue to work at half power in case over voltage and one or two amplifier cards fault.

6.        Front panel meter continuously display output power, reflected power, power supply voltage and power supply current.

7.        Meets or exceeds international standard for safety and electrical specifications.
