470--862MHz broadband response and low noise design
Design of low power consumption and linearization advances emitting power of the transmitter and reduces nonlinear distortion.
Very low group delay feature, suitable for digital signal transmission.
ALC keeps output of constant power, output VSWR detecting protection
Apply to single-channel or multi-channel UHF digital television transmission system
Be used in the broadband repeating of HFC, AML, or MMDS digital TV signal
Realize wireless network coverage of digital TV at a low cost.
Modular design simplifies installation, field services and upgrade.
Automatic and manual switching backup systems available.
Build-in lightning protector with current-dividing series power prevents lighting surge and instant overvoltage.
Local monitoring and control.
Wireless remote monitoring and control (Optional)
