GQE-LPF-D specifications:
- The DC bias (D) configuration features 25 lines with 20 Hz cutoff frequencies and an in-line resistance of 103 Ω.
- Ideal for filtering small (~mA) bias currents to sensitive devices.
- All lines feature 2-pole RC and four stages of 7-pole LC filtering.
- Input connector: 25-socket (female) D-sub micro • Output connector: 25-pin (male) D-sub micro
- Insertion loss: > 60 dB for 1 MHz – 1 GHz, > 50 dB for 1 – 20 GHz (typ.)
- Lines 1-25: 20 Hz cutoff
- Resistance: 103 Ω (typ.)
- Insertion loss at 60 Hz: > 13 dB (typ.)
- Operating limits: 10 V or 50 mA (max.)
- Isolation from ground: > 100 MΩ (typ.)
- Recommended applications: Aggressive filtering of DC bias lines to qubits, JPAs, TWPAs, and other sensitive quantum devices. Not recommended for transport measurements.
