201406-01

The 201406-01 from Millimeter Wave Systems is a Cryogenic Bias Tee that operates from 2 to 8 GHz. It is specifically designed to provide reliable DC biasing performance down to 10 mK, making it suitable for cryogenic superconducting systems. This bias tee features niobium-titanium superconducting inductors that ensure near-zero power dissipation below 9.7 K, thereby eliminating parasitic heat load on sensitive cold stages. The inductor also provides enhanced bandwidth supporting DC modulation up to 500 MHz, making it ideal for qubit control in quantum computing or LNA modulation biasing Dicke radio astronomy receivers. 

The 201406-01 cryogenic bias tee has an insertion loss of 0.5 dB and a return loss of 15 dB. It can handle an input voltage of up to 50 V DC and draws 225 mA of current. This bias tee is available in a gold-plated OFHC module measuring 1.00 x 1.39 x 0.38 inches and has an SMA (male) connector for the RF + DC port & SMA (female) connectors for the RF and DC ports. This housing material is designed to ensure excellent thermalization to the base temperature.
