Vna measurments pending…. done -25dB S11@1GHz -> cutting radiating element And this is my plan
The idea is to switch caps parallel for impedance matching purposes. And it works 🙂 See what you habe learned in your rf class!
A flexible current source was needed for pa biasing. Works 🙂
The Rigol DP832 was used as a very poor SMU (source measurement unit) to characterize a n-channel mosfet (enhancement). It can be seen, that the device has been touched (discontinuities in the curves). 1mA resolution is also to less for device characterization but … Weiterlesen
