Can HMC565 and HMC997 have their supplies switched dynamically to switch transmission and reception paths?

Hi,

 

We have a loop made of these two amplifiers. However, they are on diferent paths isolated with RF swtiches. These switches are not sufficient to grant isolation though. For this reason an oscillation occurs at around 22 GHz. To compensate this, we thought that we could switch the amplifiers on and of.  HMC997 on and HMC565 off for transmission and HMC565 on and HMC997 off for reception. Such would occur at around 5 kHz.
