radar slip ring

hi
if we use rotating phase array radar with 120 channel.
and we like to transmit IF (100MHz) frequency to the DSP on nonaction part of system.
can we use slip ring with 40dB isolation.

I would suggest that instead of using a slip ring you look at something similar to the method used by the rotating heads of video tape recorders. These use a circular transformer with one part stationary, the other rotating. Another option would be to use the IF to modulate a laser and transmit to diode detector. This could shine down the centre of the shaft so its not moving with the phased array.

Hi,
We supplied slip ring to radar application before.

Are all the 120 channel transferring signals?
please tell me if the slip ring need through bore? If yes,please kindly let me know the hole size.

Have any other size requirements?

Meanwhile,I also need to know the Voltage?

hi
we need hollow shaft slip ring .
max power we need is 30dBm and all of ring has been for signal transmission.
min inner hole size is 5cm.
thank

Hi,
Could you tell me your e-mail and other information? I will transfer your requirements to JINPAT technical engineer.
