Measured performance of the cryogenic LNAs at 15 K physical temperature.
| Amplifier | Band | Tn(av.) | G(av.) | IRL(80%) | ORL(80%) | Pdiss |
|---|---|---|---|---|---|---|
| serial number | (GHz) | (K) | (dB) | (dB) | (dB) | (mW) |
| YMWN 2006 | 72–116 | 30.7 | 25.6 | −6.3 | −13.7 | 23.2 |
| YMQ 2002 | 31–50 | 15.1 | 33.8 | −5.1 | −12.0 | 14.8 |
Notes. The values of noise temperature (Tn) and gain (G) are the average value in the band, while the values of the input and output reflection losses (IRL, ORL) are the worst case in 80% of the band. Pdiss is the total heat power dissipation at the optimum bias value.
