RF Microwave Filter Manufacturer

Since 1999, Bree Engineering has been satisfying customers by supplying custom RF filters in varying sizes. Bree Engineering builds all of our parts to order, and we welcome special requests. We also have special surface mount package designs for lumped element filters. The special surface mount packages provide excellent performance, delivery, and competitive pricing. We are proud to service Commercial, Industrial and Defense markets.

All Bree Engineering products are developed, built and tested at our facility in San Marcos, California. Bree Engineering supports small prototype requirements and we have sustained large production runs exceeding 10,000 filters per week. We have a very fast response time for all quote requests, and we can help at any stage of your RF system design. Based on the desired request we will provide accurate and reliable simulations reflecting what will be seen on the test bench.

Bree Engineering offers a wide range of RF filters. A majority of our filter designs are based on cavity and lumped element configurations with varying connector pins. We are capable of making Lowpass, High pass, bandpass, and band reject filters. Due to designing and manufacturing many different types of RF Filters it would be best to view our Custom Filter Page to see what we can do. Please contact our technical sales representative for additional electrical and mechanical requirements, or if you have any questions.

We have been featured in many industry publications including Wireless Design Magazine, rfcafe and others.
