AD603-EVALZ

AD603-EVALZ is an evaluation board for AD603 variable gain amplifier. AD603 is a low noise, voltage-controlled amplifier for use in RF and IF AGC systems. The AD603 evaluation board has built-in flexibility that allows convenient configuration to accommodate most operating configurations. Any dual-polarity power supply capable of providing 20mA is all that is required, in addition to whatever test equipment the user wishes to perform the intended tests. The board is shipped with the gain at minimum, with a 0 ohm resistor installed in R3. For maximum gain, simply remove R3. Because of the architecture of the AD603, the bandwidth decreases by 10, but the gain range remains at 40dB. Intermediate gain values may be selected by installing a resistor between the VOUT and FDBK pins.
