TGA4539-SM
Ka-Band 1 Watt Power Amplifier
Load Pull Data
RF performance of the TGA4539-SM is optimum when placed in the impedance environment specified below. These
impedances are NOT the impedances of the device; they are the impedances presented to the device via an RF circuit or
load pull system. Z
Product Information page.
The power data points shown below were measured in a load pull system. The power data points shown in ‘Typical
Performance’ were measured using the input and output structures shown in ‘PC Board Tuning Layout’ and can vary from
the load pull measurements.
