... RF choke be connected between the supply voltage and the output pin, RFOUT. This increases the dc voltage applied to the collector of the output amplifier stage, which improves performance of the AD8353 to be very similar to the performance produced when used for the supply voltage. The inductance of the RF choke should be approximately ...

... LOCAL OSCILLATOR Figure 38. AD8353 Driver Amplifier LOW FREQUENCY APPLICATIONS BELOW 100 MHz The AD8353 RF gain block can be used below 100 MHz. To accomplish this, the series dc blocking capacitors, C1 and C2, need to be changed to a higher value that is appropriate for the desired frequency. C1 and C2 were changed to 0.1 μF to accomplish the sweep in Figure 39 ...
