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.

A matching aluminum die cast enclosure is available (111x64x37 mm): https://www.sv1afn.com/en/products/die-cast-111-67-37-box.html

The distance between the two connectors center to center is 39 mm.

An encased filter inside an aluminum die-cast box is also available: https://www.sv1afn.com/en/products/10-mhz-crystal-filter-1-1.html
