XTest1¶
Device Description¶
XText1 is a simple test board intended to demonstrate the some of the basic parts of the AttenuatorX project, and allow measurement of signal changes over a variety of frequencies and power levels.
XTest1 makes has two main RF paths:- The main switching and active attenuation path. This path has two inputs (one for lower power, and one for higher power, immediately attenuated by 20dB), and a single output.
- An insertion loss path used to measure the insertion loss of the switch and active attenuator
The RF Switch and the active attenuator are controlled by an AVR ATMega48PA/88PA/168PA microcontroller.
