12 bias circuit a schematic of the basic, unmatched bias circuit for the agb series gain blocks is shown in figure 33. the rf input and output terminations are 50 ? . inductor l1 provides dc power from v supply 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 34, for improved stability or to serve as a voltage drop for operation from higher supply voltages. matching for rf performance the AGB3301 gain block amplifer can be used in many fxed 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 2400- 2500 mhz ism band, and the 2500-2686 mhz mmds band. reactive matching circuits may be designed for figure 33: unmatched bias circuit figure 34: bias circuit with optional feedback/voltage drop resistor 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 35 and 36 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. 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 AGB3301 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 11 depicts the raw magnitude and angle data for an unmatched AGB3301 over the 50 to 3000 mhz frequency range of operation. data is shown in 100 mhz steps, with a characteristic impedance of 50 ohms, v dd = +9 v, and at t a = +25 o c. gain block l1 c1 c2 c3 rf input rf output v supply v dd l1 c1 c2 c3 rf input rf output v supply r1 v dd gain block data sheet - rev 2.2 03/2012 AGB3301
