  1. 336 GHz Phase Sensitive Transceiver Vector Voltmeter VDI 336 GHz Tx VDI 336 GHz Rx

  2. 336 GHz Phase Sensitive Transceiver Phase (deg) Magnitude (dBm) 336 GHz Virginia Diodes

  3. 336 GHz Phase Sensitive Transceiver • 336 GHz Transmitter • 17 mW output power • 336 GHz Receiver • Mixer conversion loss 10.5 dB (SSB) • Mixer noise temperature 1300 K (SSB) • Fully phase-locked system • System dynamic range 94 dB • Up to 104 dB with slight compression • Dynamic range limited by Lock-in noise floor • VDI Tx-Rx has much larger dynamic range (at least 20 dB higher) Virginia Diodes

  4. Tx-only Amplitude Stability Turn-on transient Air-handler turning on Thru the night Measured with Erickson calorimeter Virginia Diodes

  5. Full Tx-Rx 336 GHz Stability Turn-on transient Virginia Diodes Stability of full system with Lock-in

  6. Full Tx-Rx 336 GHz Stability Virginia Diodes

  7. 336 GHz Phase Sensitive Transceiver • Systems show excellent stability after initial warmup • Amplitude stability • Standard deviation ~0.005 dB • Phase stability • Standard deviation ~0.4 deg over minutes • Long term phase drift 3-5 degrees over hours Virginia Diodes
