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 VSUPPLY C3 C1 C2 Gain Block VSUPPLY C3 R1 L1 C2 Gain Block 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. 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. Figure 21: Unmatched Bias Circuit RF Input 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. RF Output VDD C1 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.
