function of frequency and the attenuation and the dephasing as a function of strain were characterized. Also, to properly characterize and compare the SWCNT device with the more complex bi-layer SWCNT device, a measurement test-bench, based on a low frequency VNA (Vector Network Analyzer), was chosen for the second device.

The lower frequency IF signal has less insertion loss from the cable run to the VNA. For long distances, this will significantly reduce the in-sertion loss: the same cable with 4 dB/m loss at 40 GHz may only have 1 dB/m loss at 4 GHz. While this approach reduces the loss of the received signal from the VNA, the cable carrying the LO sig-
