ADL5323
BASIC CONNECTIONS
Figure 16 shows the basic connections for operating the
ADL5323. Each of the three power supply lines should be
decoupled with 10 μF, 10 nF, and 100 pF capacitors. Pin 3, Pin 6,
Pin 7, and the exposed paddle under the device should all be
connected to a low impedance ground plane. If multiple ground
planes are being used, these should be stitched together with
vias under the device to optimize thermal conduction. See the
recommended land pattern in Figure 13 for more information.
WCDMA DRIVING APPLICATION
Figure 14 shows a plot of the spectrum of an ADL5323 driving a
single carrier WCDMA signal (Test Model 1-64) at 0 dBm,
centered at 2140 MHz. At 5 MHz offset, an adjacent channel
power ratio of −74 was measured.
