Active Project: AAZ-0217 (Full Kits and
Measuring antenna impedance or line losses is
of a great interest to Radio Amateurs. That too when it comes to
measure an antenna performance without having a transmitter, it
brings special attention of homebrewers.
This project uses AD9850/51 as a Signal Generator
and AD8307 as a detector and works with a resistive return-loss
Look simple but it is made so by our friend Tony
/ I2TZK who spent a lots of time in making Firmware and PC
software for this project.
Antenna Analyzer: AAZ-0612 is designed on a
double sided PTH board measuring 11x6.5CM and its a full USB device.
A special PC software is developed by Tony / I2TZK
which, when installed on your PC, gives you a graphical presentation of
how good your antenna is!!
To further cheer-up homebrewers, we have made a
small carrier board for SSOP28 package of AD9850/51. AAZ-0912 kits
are supplied with DDS chip pre-soldered on carrier board to make assembly of
this kit without much pain.
Purpose of this project is to
encourage radio amateurs to build their own Antenna Analyzer at a low
PC Software (WinXP/WIN7) & PIC Firmware
AAZ-0612 has achieved
following design task:
Single Micro Controller with built-in A/D
Based signal Generator. Act as a signal source too
