IR-Filter Gold-plated OFHC copper with SMA connectors

IR-Filter

Infrared-Filter for Microwave Signals

YQ-IR-110A | DC – 10GHz, 50Ω

In stock – Contact us to order

This reliable infrared filter protects the coherence of your qubits by blocking high-energy radiation. Our filters are manufactured using a simple, patent-pending process that ensures consistent transmission and reflection parameters across multiple units.

For versions with different attenuation levels or connector interfaces, please contact YQuantum.
