Notes:
Use 0.003” by 0.0005” Gold Ribbon for bonding. RF input and output bonds should be less than 0.015” long with stress relief.
Detector delivers 0.1V DC into 3k Ω load resistor for >+17 dBm output power. If output power level detection is not desired, do not make
connection to detector bond pad
Characteristic performance data and specifications are subject to change without notice.
