UM10484, Integrated Demonstration (Demo) Board for Clean-Up-PLL (CUP) local oscillator generator TFF1003. The demo board includes an output buffer amplifier based on the BFU7XX series of microwave transistors. The demo board converts a reference signal (typically 10 MHz) to a frequency of 30 MHz to 50 MHz via a Xilinx CPLD and logic gate-based Voltage-Controlled eXternal Oscillator (VCXO). The fifth harmonic is filtered via a 7th-order Cauer filter and used as the reference for the TFF1003. Microwave transistors BFU7XX amplify the output of the TFF1003 to a level of 7 dBm, 10 dBm or 13 dBm, depending on the version of buffer used
