Comment on Low-cost 60GHZ phased array antennaparent

With 22dBi they're quoting, it'd have to be all Tx or all Rx. Unless they're conflating amplifier gain in there, which sometimes happens.

The block diagram didn’t show a switch, and the NF is 6 dB, so I figured it was separate. I have used the HMC-6301, which has about the same NF. The switches get quite lossy at mmWave.
