AC INTERFACES
Because of the AD8343’s wideband design, there are several
points to consider in its ac implementation; the basic ac signal
connection diagram shown in Figure 55 summarizes these
points. The input signal undergoes a single-ended to differential
conversion and is then reactively matched to the impedance
presented by the emitters of the core. The matching network
also provides bias currents to these emitters. Similarly, the LO
input undergoes a single-ended-to-differential transformation
before it is applied to the 50 Ω differential LO port. The differential
output signal currents appear at open-collectors and are reac-
tively matched and converted to a single-ended signal.
