Shajedul Hasan University of Tennessee - Knoxville This Thesis is brought to you for free and open access by the Graduate School at Trace: Tennessee Research and Creative Exchange. RF power presents compelling advantages. The signal generators output power is ad-justed at each of the specified frequency steps across the test band. The main component is a MECA -20/-20 dB Directional Coupler which has a frequency range of approximately 700 MHz to 2. illuminated meter on top gives an indication that they are on and also shows what they are doing. 0 October 2013 ©2013 Semtech Corporation www. The ferrite core transformer splits and the RF line goes through the center. As shown in the Figure 2 block diagram, the RF section of the QBS-609 consists of driver amplifier AR1 and GaN 1kW output amplifier AR2. 2011 6 TEST BLOCK DIAGRAM 1 RF Input (P in) 2 Gate Voltage (V. The block diagram for the project is as follows. To see available part numbers and datasheets, simply mouse over each block and a list will appear.
