We ve worked our way up to the RF amplifier deck. Now, start by working on the input circuit. At this point, you should be reasonably certain the power supplies are functioning correctly, and that the ...

A PLL is overkill for some applications, however, especially if the input frequency needs only to be doubled. For those cases a simpler approach”such as the circuit in Figure 1″ will do the job just ...

Figure 2 shows a 10MHz reference input circuit using the LTC6957-3, which produces two in-phase CMOS outputs. The transformer shown in Figure 2 serves several functions. First, in conjunction with the ...
