Impedance matched absorptive thermal blocking filters [PDF]
Review of Scientific Instruments, 2014 We have designed, fabricated, and characterized absorptive thermal blocking filters for cryogenic microwave applications. The transmission line filter's input characteristic impedance is designed to match 50 Ω and its response has been validated from 0 to 50 GHz.
