    The transmitter adopts a low-cost design concept, integrating the exciter and power amplifier, output filter, switching power supply, etc. in a 2U high 19-inch standard chassis.

     Functional features

l2U 19-inch thick aluminum alloy case, which is not only sturdy but also has good heat dissipation.

lPrecise PLL frequency generation system to ensure the frequency does not drift within at least 10 years.

lExcellent 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.

lSupport external input modulation RDS or SCA signal.

lEquipped with RS232 communication interface, users can control all operations through the transmitter communication protocol.

lRF amplifier uses  LDMOS transistor , making it able to withstand severe load mismatch of more than 65: 1 VSWR at 5dB compression point.
