Portable digital video COFDM transmitters, such as the BMS 2GHz CarryCoder II, are used 
behind the camera in security and law enforcement live video transmission. These transmitters 
can only provide a medium RF power (e.g. < 1W), limiting the distance between the event site 
and 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-7 will increase the RF power to the 
maximum 5W without adding spurious signals and distortions to the transmitter output. The 
power amplifier output is directly connected to the 2GHz transmitting antenna.  

A typical transmitter application of the 1.99–2.5GHz power amplifier is shown in Figure 5. A 
practical application is shown in Figure 6. The output of the PA is directed to the transmitting 
antenna located on the roof of a mobile vehicle. The receiver antenna can be located on a mast 
to result in better coverage over longer distance.
