10 MHZ Band-Pass Monolithic Crystal Filter (Tested & Encased in a 111x64x37 mm box)

• 50 Ohm in/out SMA or BNC ports
• ​Bandwidth of 1 KHZ (+/- 500 HZ) @ -3 dB
• Bandwidth of 10 KHZ (+/- 5 KHZ) @ -60 dB
• Pass-band ripple 0.5 dB
• Insertion loss: 3 dB max
• Compact 111x64x37 mm size
• Supplied built & tested

Here is a 10 MHZ band-pass filter (-3dB bandwidth of 1 KHZ) to be used mainly for a lab's reference frequency signal clean-up. It greatly improves phase noise!

It can also be used to filter out  harmonics of square wave oscillators and generators for converting their waveform to sine, for isolation improvement, even for selecting  the 10 MHZ time signals in receiver front-ends.

Think about placing two of them in series for further narrowing the bandwidth.
