Low noise, wide band MgB2 hot electron bolometer mixer at 5.3 THz and 20 K
Paper in proceeding, 2022

We present a low noise and wide band superconducting MgB2 hot electron bolometer (HEB) mixer characterized at 5.3 THz and 20 K, where a DSB receiver noise temperature of 2920 K is obtained and an IF bandwidth is 9.5 GHz. The frequency of 5.3 THz represents the highest frequency, where an MgB2 HEB mixer has ever been characterized at so far, providing an insight to their applicability for probing important higher frequency molecular/atomic emission lines. The operating temperature of 20 K enables an HEB mixer to operate in compact, low power consumption coolers, which can significantly reduce the cost and complexity of any relevant instruments specially in the case of space, where tight supply conditions and limitations apply.
