Portable digital video COFDM transmitters, such as the BMS 2GHz CarryCoder II, are used 
behind the camera in electronic news gathering (ENG) for mobile broadcast auxiliary stations 
(BAS). 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-10CC-7 will 
increase the RF power to the maximum 10W 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 PA 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 the roof of a mobile vehicle. The receiver antenna can also be located on a mast to 
result in better coverage over longer distance.
