8 / 12 page ADL5323 Rev. 0 | Page 8 of 12 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. Figure 13. Recommended Land Pattern 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. –15 –115 CENTER 2.14GHz SPAN 14.6848MHz 1.46848MHz/ –50 –60 –70 –80 –90 –100 –30 –40 –20 –110 RBW = 30kHz VBW = 300kHz SWT = 2s RF ATT = 10dB CH PWR = 0dBm ACP UP = –74.2dBc ACP LOW = –73.9dBc Figure 14. Spectrum of Single WCDMA Carrier Centered at 2140 MHz; Carrier Power = 0 dBm, ACPR = −74 dBc Figure 15 shows how ACP varies with output power level. Note that in this plot, the noise floor of the spectrum analyzer was factored out. –55 –80 –15 OUTPUT POWER (dBm) 20 –60 –65 –70 –75 –10 –5 0 5 10 15 Figure 15.
