Description
Quartz Crystal Filter Narrowband Band-Pass Filter 10.7MHz±7KHz SMA-KE Connector
Introduction:
- Screening: Not the crystal you used can work as a filter. After resonance frequency point and physical fitness detection, only 25% of crystals can be used.
- Pairing: Crystals must be paired to achieve the best working performance. Only 30% of batches can be paired successfully.
- Design: Crystal filter circuit design. The input impedance of crystals changes greatly, which matches the circuit design.
- Debugging: The characteristics of each crystal are not exactly the same. We must manually perform accurate debugging according to the impedance characteristics.
- Instrument: The bandwidth of the crystal filter is particularly narrow. Special instruments are required. General oscilloscopes and spectrum analyzers cannot be used.
Technical Parameters:
- Working Frequency: 10.7MHz±7KHz
- PCB Board Size: 24 x 47mm
- Out-of-band Rejection: > 80dB (BW <200kHz); > 60dB (BW<11KHz)
- Connector Type: SMA-KE (Shape and inner hole can be customized)
- In-band Fluctuation: <1.0dB
- System Impedance: 50 ohms
- Insertion Loss: 2.0dB (Typical)
Package Included:
- 1 x Crystal Filter
Precautions:
1. The input and output ports are 50 ohms. It is only applicable to 50 ohm systems.
2. The components are precisely matched and need professional instruments to debug.
3. Any modification may damage the filter.
4. The crystal is a precision device. It is strictly forbidden to bump, shake, overheat and cold, and temperature shock.
5. Each filter is manual and precise debugging, slightly different in performance. Please make sure that you don't mind before purchasing. Thank you!
