ADL5202-EVALZ is a fully populated, 4-layer, FR4-based evaluation board. For normal operation, it require a 5 V power supply capable of delivering 500 mA and a 3.3 V power supply capable of delivering 1 mA. The 5 V supply is connected to the test loops labeled VPOS and GND. This is the bias for the main amplifiers. The open collector outputs are connected to the main bias via the power plane. The 3.3 V supply is connected to the test loops labeled 3.3 V and GND. The RF input is applied to the SMA connectors labeled INA- and INB-. The RF output is available at the SMA connector labeled OUTA- and OUTB-. A fully differential input and output is easily configured by removing R8, R9, R79, R80, installing a zero ohm jumper at R81, R82, R88, R89, removing transformers, T1, T2, T3, T4 and placing jumpers across the transformer pads. The evaluation board can be programmed through the USB port of a PC running Windows XP or Vista with Microsoft .NET Framework 3.5 installed. The required control software can be downloaded from www.analog.com. Manual operation of the gain control functions is possible using the 3 pin headers and supplied jumpers. Power up is controlled using the 3 pin header labeled PWUPA and PWUPB or an external control signal maybe applied using the SMA connectors labeled PWUPA and PWUPB.
