Cavity bandpass filters – broad frequency selection and custom design | JQL Electronics / Dorado
JQL cavity bandpass filters for RF, microwave and mmWave applications. Broad frequency selection, multiple interfaces and custom filter design available.
JQL Technologies cavity bandpass filters are designed to transmit defined RF and microwave frequency ranges while suppressing unwanted signals outside the required passband. The portfolio includes a broad selection of standard configurations for applications ranging from VHF/UHF frequencies to microwave and mmWave systems.
Available models differ in terms of passband, insertion loss, rejection, return loss, operating temperature and RF interface. Depending on the reference, configurations include SMA, N, 7/16, Mini-UHF, K/2.4 mm, drop-in and PIN interfaces.
In addition to catalogued products, JQL supports custom bandpass filter designs. Manufacturer-defined design parameters include frequency band, insertion loss, rejection and isolation.

Additional information
The electrical specifications vary significantly between individual JQL references. Passband, insertion loss, rejection, return loss, power, temperature range and connector therefore need to be matched to the specific application.
For requirements that cannot be covered by a standard model, JQL provides custom-design capabilities based on the required filter type and electrical target parameters. Frequency band, insertion loss, rejection and isolation can be defined as key design criteria.
EMCO Elektronik supports the selection of the appropriate JQL bandpass filter and the technical matching of the filter characteristics to the application. This includes evaluating the required passband, out-of-band rejection, insertion loss, RF interface and mechanical or system-level integration requirements.
