In my application the HMC960 follows an IQ mixer HMC908. I have noticed that HMC960 is very sensitive to 50Hz just approaching the chip with a finger, pencil ot screwdriver (the output almost saturates). All the power supplies are linear. The 50Hz appears on the outputs even without RF applied to the mixer.

The PCB is a 4 layer and similar to the application board
