Construction of 12 GHz LO (DB6NT) for coming 24 GHz transverter
Status: finished 19980718
Output: approx. 50mW (my power meter is not calibrated at 12GHz)
Frequency: 11880 MHz (for 24192 MHz with 432 MHz IF)
Tips for the construction:
- Don't forget to make all the thru-connect via's before placing the SMDs
- Follow the tuning procedure given by DB6NT (using measure points M1 - M4), and do not try to tune the non-GaAs stages using the 12GHz output as indicator. The stages are in so high saturation that this will tune the helix-filters off frequency.
