PRODUCTION DATA
The AMP EN jumper (J4) controls the amplifiers disable function on pin 3 of the device. It is set to V+ by default using resistor R13 and can be shorted to V- with jumper J5.
For high-speed testing, C4 can be replaced with 0 Ω to terminate the PD SMA input with a 50 ohm resistor in R10. The shorting block should be removed from J5 during high-speed testing. Because 0 Ω at C4 terminates to the ground and not to the supplies. The state of the amplifier will be undefined when the signal source is disconnected. For this reason, 0 Ω at C4 should only be used when driving the SMA connector with a high speed, controlled impedance source.
