Electrical Specifications
The electrical specifications apply at TA=+25°C in a 50Ω system. Typical data shown is for the NLTL used in the forward direction with a +20 dBm 1GHz sine wave input and no bias resistor (open circuit) unless otherwise stated. Square Wave input generated using either the ADM1-0026PA or the APM-7098PA amplifier at +7V/-0.3V and +8V/+8V respectively. Min and Max limits apply only to our connectorized units and are guaranteed at TA=+25°C. All bare die are 100% DC tested and visually inspected.

[1][2][3][4][5] The Highest Frequency Harmonic Output was determined as the highest frequency harmonic that was above a -60dBm threshold as seen on a spectrum analyzer.
[6] Input power to square wave driver amps is lower but high enough to saturate the amplifier. Power levels in square wave plots refer to input power to the amplifier, not the amplifier’s output power.

Input power levels refer to drive level going into the NLTL chain input in Application Circuit. Square wave plots are referenced to drive level entering the square wave driver amplifier, not the output power of the amplifiers.
