Hzbeat’s Typical Microstrip Circulators span S/C/X/Ku/K/Ka bands (roughly 2–40 GHz), balancing compact size, low insertion loss and stable isolation for high‑integrity non‑reciprocal routing. They are widely applied in 5G radios, radar front‑ends, satcom terminals and industrial RF systems.

The series includes multiple T‑junction and Y‑junction realizations, with clockwise and counter‑clockwise variants. Models emphasize low insertion loss (≈0.5–0.7 dB), isolation ≈18–20 dB (band‑dependent) and broad temperature range (−55 °C to +85 °C).

• 5G / 5G‑Advanced radios (mid‑band, small‑cell)
• Radar front‑ends where SWaP matters (airborne, vehicular)
• Satellite ground terminals and up/down‑link chains
• Medical MRI and RF therapy equipment
• Industrial RF instrumentation and analyzers

• Compact & light — Minimal spatial discontinuity when integrated with microstrip circuits; reliable 50 Ω bridging.
• Wide span — 2–40 GHz coverage across S/C/X/Ku/K/Ka bands.
• Consistent performance — Low insertion loss, stable isolation & VSWR across temperature.
• Direction options — CW and CCW variants available for each band.
