The RF input and output terminations are 50W. Inductor L1 provides DC power from VSUPPLY and serves as an RF choke to maintain desired AC performance. The input capacitor C1 and output capacitor C2 are RF blocks that isolate DC current from adjacent circuits. Capacitor C3 is used as an RF bypass that minimizes noise from the supply. In some applications, a feedback resistor R1 may be added in series with L1, as shown in Figure 22, for improved stability or to serve as a voltage drop for operation from higher supply voltages. Matching for RF Performance The AGB3300 Gain Block amplifier can be used in many fixed wireless frequency bands, such as the 824-894 MHz U.S. cellular bands, the 1850-1990 MHz PCS band, the 880-960 MHz GSM band, the 24002500 MHz ISM band, and the 2500-2686 MHz MMDS band. Reactive matching circuits may be designed for both the input and output, in order to optimize the RF performance for a particular application. For example, gain, linearity (OIP3) and return loss may be improved over a particular frequency band of interest. Recommended matching circuits for various applications, as well as wideband S-parameters to use in the simulation of custom designs, are included in this data sheet. For a particular application not addressed in the data sheet, please consult with an ANADIGICS Sales Reperesentative or Application Engineer. Evaluation Boards A versatile evaluation board that enables users to measure actual device performance has been developed for the AGB Series Gain Blocks. The generic layout allows the user to implement a wide variety of matching circuits, in order to assess performance for a particular application. The evaluation board is 1.0 square, and is fabricated on 0.031 thick FR-4 material. Figures 23 and 24 show the via hole locations and the layout pattern on both sides of the evaluation board. The vias have a 0.010 diameter and are plated through. To request an evaluation board, please contact an ANADIGICS Sales Reperesentative or Application Engineer. RF Output VSUPPLY C3 L1 C1 RF Input Gain Block VDD C2 Figure 21: Unmatched Bias Circuit VSUPPLY C3 R1 ESD Sensitivity Electrostatic discharges can cause permanent damage to this device. Electrostatic discharges accumulate on test equipment and the human body, and can discharge without detection. Although the AGB3300 has some internal ESD protection, proper precautions and handling are strongly recommended. Refer to the ANADIGICS application note on ESD precautions. S-Parameter Data Table 8 depicts the raw Magnitude and Angle data for an unmatched AGB3300 over the 50 to 3000 MHz frequency range of operation. Data is shown in 100 MHz steps, with a characteristic impedance of 50 Ohms, VDD =+5V, and at TA = +25 oC. 9 L1 C1 RF Input Gain Block VDD C2 RF Output Figure 22: Bias Circuit with Optional Feedback / Voltage Drop Resistor Data Sheet - Rev 2.1 06/2003 AGB3300 Figure 23: Evaluation Board - Front (not to scale) Figure 24: Evaluation Board - Back (X-ray) (not to scale) 10 Data Sheet - Rev 2.1 06/2003 AGB3300 Table 8: AGB3300 S-Parameters in Unmatched 50 Ohm Test Fixture (TA = +25 oC, VDD = +5 VDC) FR E Q (MH z ) 50 100 200 300 400 500 600 700 800 900 1000 1100 1200 1300 1400 1500 1600 1700 1800 1900 2000 2100 2200 2300 2400 2500 2600 2700 2800 2900 3000 S11 (dB MAG) -6.507 -6.516 -6.499 -6.462 -6.321 -6.193 -6.069 -5.918 -5.799 -5.673 -5.536 -5.445 -5.285 -5.19 -5.156 -5.013 -4.973 -4.901 -4.864 -4.746 -4.758 -4.733 -4.72 -4.66 -4.661 -4.67 -4.626 -4.665 -4.662 -4.596 -4.666 S11 (AN G) -12.154 -21.537 -37.572 -56.814 -75.224 -90.589 -108.151 -125.263 -138.915 -154.339 -169.301 178.252 164.881 151.443 139.857 127.266 115.149 104.933 93.099 81.62 71.768 60.555 49.351 40.498 29.484 19.357 10.28 -0.209 -10.192 -19.107 -29.431 S 21 (dB MAG) 14.964 14.938 14.848 14.678 14.466 14.25 13.984 13.707 13.394 13.041 12.708 12.392 12.037 11.685 11.422 11.046 10.714 10.468 10.137 9.833 9.484 9.188 8.907 8.584 8.432 8.131 7.875 7.63 7.261 7.164 6.893 S 21 (AN G) 176.966 165.739 151.75 135.918 120.64 107.667 92.666 78.515 66.311 52.299 38.708 27.223 13.929 1.033 -10.447 -23.162 -35.782 -46.033 -58.549 -70.871 -80.859 -93.112 -104.888 -115.301 -127.035 -137.912 -148.337 -159.328 -171.146 178.737 166.983 S 12 (dB MAG) -23.579 -23.564 -23.387 -23.178 -22.937 -22.678 -22.296 -21.947 -21.649 -21.261 -21.075 -20.812 -20.56 -20.492 -20.149 -20.1 -19.864 -19.514 -19.576 -19.265 -19.384 -19.29 -19.006 -19.022 -18.507 -18.696 -18.497 -18.372 -18.689 -17.696 -17.839 S 12 (AN G) -3.305 -5.944 -10.36 -16.337 -22.557 -28.753 -35.997 -43.455 -50.872 -58.948 -66.809 -75.068 -83.033 -92.649 -100.693 -109.435 -120.033 -126.161 -135.294 -145.479 -152.04 -163.395 -171.556 179.522 171.397 164.208 154.449 147.906 136.067 127.671 118.77 S 22 (dB MAG) -31.971 -31.461 -29.431 -26.939 -24.401 -22.759 -21.099 -19.896 -19.241 -18.584 -17.833 -17.221 -16.652 -16.25 -16.075 -15.862 -15.582 -15.199 -14.922 -14.533 -14.52 -14.288 -14.322 -13.985 -13.94 -13.689 -13.64 -13.403 -13.335 -13.292 -13.19 S 22 (AN G) -85.979 -93.498 -106.651 -123.756 -139.597 -149.93 -165.124 -175.768 173.368 160.892 148.221 138.722 128.112 118.653 108.597 98.578 86.244 78.227 68.761 60.412 52.482 43.001 32.986 24.914 16.121 7.138 -0.294 -9.789 -18.904 -27.542 -37.144 K Factor 1.220 1.221 1.207 1.194 1.172 1.151 1.121 1.093 1.079 1.059 1.051 1.040 1.026 1.035 1.022 1.032 1.031 1.007 1.033 1.010 1.055 1.067 1.065 1.084 1.046 1.091 1.090 1.102 1.178 1.067 1.119 Data Sheet - Rev 2.1 06/2003 11 AGB3300 PACKAGE OUTLINE Figure 25: S24 Package Outline - SOT-89 Figure 26: Branding Specification 12 Data Sheet - Rev 2.1 06/2003 AGB3300 NOTES Data Sheet - Rev 2.1 06/2003 13 AGB3300 NOTES 14 Data Sheet - Rev 2.1 06/2003 AGB3300 NOTES Data Sheet - Rev 2.1 06/2003 15 AGB3300 ORDERING INFORMATION PAR T N U MB ER AGB3300S24Q1 TEMPER ATU R E R AN GE -40 to +85C PAC K AGE D ESC R IPTION SOT-89 Package C OMPON EN T PAC K AGIN G 1,000 pi ece Tape and Reel ANADIGICS, Inc. 141 Mount Bethel Road Warren, New Jersey 07059, U.S.A.
