2.3 Output

Monitor the EVM output by using the SMA connector labeled Vout or the test point labeled Vout. Resistor R3 is used as an isolation resistor on the OPA202 output to improve circuit stability while driving high capacitive loads greater than 1 nF. Resistor R3 can be removed if no capacitive load drive is required.
