We bought these miniature cavity bandpass filters for a project but never installed them. Manufacturer P/N ZVBP-2300A-S+ has SMA female connectors and a frequency range of 2.2-2.4 GHz from the factory. They have been tested and tuned and work great.
Center passband was changed for our project and is currently set to 2034.5 MHz, but has the ability to be tuned back to manufacturer frequency range with proper equipment.
The filters are current production and list for $324.00 on the Mini-Circuits website. We have (3) available for sale.
Note: The + in the part number denotes RoHS (lead-free) compliance.
