LTCC Bandpass Filter - 3600~4000MHz

Our model filter is a high-performance LTCC bandpass filter manufactured using advanced multi-layer low-temperature co-fired ceramic technology.

  • Wide Frequency Range: Part of our series covering 30MHz to 40GHz.

  • Compact Design: Small footprint (4.8mm × 2.5mm) for high-density SMT mounting.

  • Superior Performance: Offers low insertion loss (≤4.5dB) and high out-of-band rejection (≥28dB).

  • Durability: Operating temperature from -55°C to +85°C, suitable for harsh environments.

Applications:

  • 5G/6G Mobile Communications: Base stations and small cells.

  • Radar Systems: High-precision electronic countermeasures and radar modules.

  • Satellite Communications: Aerospace and defense RF front-ends.

  • ISM Band Devices: Wireless data transmission.
