We are happy to introduce our latest infra-red blocking filter, HERD-2. With almost 60% size reduction compared to its predecessor, HERD-1, it is now possible to have our infra-red blocking filter technology integrated into standard SMA inline wiring. Our cutting-edge filter technology ensures industry-leading in-band performance with a highly attenuating stopband. With an insertion loss of 0.13 dB below 8 GHz in room temperature and more than 65 dB of attenuation above 70 GHz, HERD-2 our highest performing filter to date. The filter consists of a gold-plated copper body with an integrated non-magnetic absorber. HERD-2 is suitable for all cryogenic applications using superconducting circuits, including superconducting and spin qubits. Pre-order HERD-2 today to ensure your setup is equipped with the finest in infra-red filtering technology!

HERD-1 is the first product that came to life at Sweden Quantum. With its industry leading 0.05 dB insertion loss up to 8 GHz it can simultaniously provide over 60 dB of attenuation at frequencies above 70 GHz. The filter consists of an aluminum body with non-magnetic SMA connectors available in different configurations. If required, it can be paired up with an extarnal, non-magnetic, 3D printed absorber. For more information you can find the datasheet and application note below. The application note contains valuable considerations of how to set up HERD-1 for ultimate performance in cryogenic system. It also contains unique data taken on transmon qubits including quasiparticle tunneling rates and radiation field temperature.
