CASE for Low Noise RF Amplifier (With battery compartment)

thingiverse

This is a compact, 3D printable case for an affordable RF amplifier available on eBay that offers a gain of 30dB and can be used as part of an EMC test toolchain. The case features a Li-Ion battery compartment, allowing the amplifier to operate without any external power supply while minimizing noise. A 5.5x2.1 charging barrel connector is also integrated into the design, which should only be charged with an 8.4VDC maximum voltage. This case serves as a great example of how to utilize the RF amplifier for EMC measurements during pre-compliance testing. For more information, refer to the EEVBlog video at https://youtu.be/2xy3Hm1_ZqI. For reference, this design was specifically created for the following amplifier: https://www.ebay.com/itm/0-1-2000MH-z-RF-Wideband-Amplifier-low-noise-LNA-Broadband-Module-Receiver-30dB/202371600929?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649 The batteries used for this project are Cellevia EEMB LP603449, which have a capacity of 1050mAh to 1100mAh. They can be purchased at https://www.soselectronic.com/products/eemb/lp603449-1-157437. A 5.5x2.1mm barrel connector is also used in this design, and it requires cutting off the left part of the flange as shown in the pictures at https://www.gme.cz/napajeci-souosy-konektor-ds-225a. The power rocker switch used has dimensions of 10.5x15mm and can be purchased at https://www.gme.cz/p-sm101-1b3.
