13 Data Sheet APPLICATIONS INFORMATION BASIC CONNECTIONS Figure 26 shows the basic connections for operating the ADL611. The device supports operation from 3 MHz to 6 GHz. However, for optimal performance at lower frequency bands, the board configuration must be adjusted. Table 6 lists the recommended board configuration to operate the device at various frequency bands. RFIN C1 RFIN 1 2 (2) ADL611 RFOUT Figure 26. Basic Connections A V dc bias is supplied to the amplifier through the bias inductor connected to RFOUT (Pin 3). Decouple the bias voltage using 68 pf, 1.2 nf, and 1 µf power supply decoupling capacitors. The typical current consumption for the ADL611 is 94 ma. At low frequencies, the device exhibits improved performance with the suggested setup configuration listed in Table 6. Figure 27 and Figure 28 provide a comparison of the performance of the device at the 3 MHz to MHz band when driven with the optimal setup configuration and the default setup configuration. 3 VPOS C6 1µF C 1.2nF C4 68pF L1 C2 RFOUT NOISE FIGURE, GAIN, P1dB, OIP3 (db, dbm) S-PARAMETERS (db) OIP3 (dbm), DEFAULT SETUP CONFIGURATION OIP3 (dbm), LOW FREQUENCY CONFIGURATION GAIN (db), DEFAULT SETUP CONFIGURATION GAIN (db), LOW FREQUENCY CONFIGURATION P1dB (dbm), DEFAULT SETUP CONFIGURATION P1dB (dbm), LOW FREQUENCY CONFIGURATION NOISE FIGURE (db), DEFAULT SETUP CONFIGURATION NOISE FIGURE (db), LOW FREQUENCY CONFIGURATION Figure 27.

14 ADL611 SOLDERING INFORMATION AND RECOMMENDED PCB LAND PATTERN Figure 29 shows the recommended land pattern for the ADL611. To minimize thermal impedance, the exposed pad on the underside of the SOT-89 package is soldered to a ground plane, along with Pin 2. If multiple ground layers exist, stitch the layers together using vias. 1.8mm Data Sheet Thermal simulation suggests a junction temperature that is 1 C higher than the top of package temperature. With additional measurements of the ambient temperature and input/output power, θja can be determined. W-CDMA ACPR PERFORMANCE Figure 3 shows a plot of the adjacent channel power ratio (ACPR) vs. POUT for the ADL611. The signal type used is a single wideband code division multiple access (W-CDMA) carrier (Test Model 1-64) at 214 MHz. This signal is generated by a very low ACPR source. ACPR is measured at the output by a high dynamic range spectrum analyzer that incorporates an instrument noise correction function..37mm.86mm.762mm.2mm.63mm.62mm 3.48mm ACPR AT MHz CARRIER OFFSET (dbc) mm.86mm 3.mm Figure 29. Recommended Land Pattern 1.27mm The land pattern on the ADL611 evaluation board provides a measured thermal resistance (θja) of 2 C/W. To measure θja, the temperature at the top of the SOT-89 package is sensed with an IR temperature gun P OUT (dbm) Figure 3. ACPR vs. POUT, Single W-CDMA Carrier (Test Model 1-64) at 214 MHz The ADL611 achieves an ACPR of 79 dbc at an output power level of dbm, at which point the device noise and not distortion begins to dominate the power in the adjacent channels. At an output power level of dbm, ACPR is still very low at 62 dbc Rev. B Page 14 of 16
