Notes:
1. 10368 MHz probe is made from the center conductor of an SMA
connector
or .141 semirigid cable. 1,8mm of the teflon
dielectric extends into waveguide.
Length of pin above dielectric is 7,6mm.
M3 tuning screw is diametrically opposite probe
and is adjustable.
2. 5760 MHz probe is 15,2
- 17,8mm in length and can be made from tubing
1,8 - 2,5mm in diameter.
3. Tuning of both frequencies
can be accomplished by tuning either probe length.
4. Isolation:
10368 MHz signal @ 5760 MHz port
= -19dB
5760 MHz signal @ 10368 MHz port
= -45dB
5. Return loss > 23dB
at both ports
