LINEAR POWER AMPLIFIER (BPA-5CC-9)
BPA-5CC-9 is a linear power amplifier with 4 watt maximum RF power and operating at 6.425 –
6.525 GHz). This power amplifier is used for increasing the transmitting range by boosting the
6GHz transmitter power to maximum 4 Watts.
Application
Portable 6GHz COFDM transmitters such as 6GHz Carry-Coder II, are used behind the camera in
Electronic News Gathering (ENG). These transmitters are only capable to provide a medium RF
power (e.g. 250mW). This seriously limits the distance between the event site and the TV relay
station. To extend the transmission range, an external amplifier is needed to boost the transmitter
power in order to compensate the path loss and ensure the acceptable Received Signal Level
(RSL) at the destination. The BPA-5CC-9 will increase the RF power to the maximum 4W, without
adding spurious and distortions to the transmitter output. The output of the power amplifier is
directly connected to the 6 GHz transmitting antenna.
