Ceramic Bandpass Filters – SMT and PIN configurations, 105 MHz to 4.9 GHz | JQL Electronics / Dorado

JQL Technologies ceramic bandpass filters are passive frequency-selective RF components designed to transmit defined frequency ranges while attenuating unwanted signals outside the passband.

The documented portfolio includes numerous models with passbands from approximately 105 MHz to 4.9 GHz. Individual references differ primarily in terms of passband, insertion loss, rejection, return loss, temperature range and interface.

Most listed models use an SMT interface, while a PIN configuration is also documented within the product family. For requirements outside the standard models, JQL provides custom-design capabilities based on defined electrical filter parameters.

Advantages

• Broad selection of passbands for different RF and wireless applications
• Compact ceramic filter technology for integration into electronic assemblies
• SMT configurations across most documented models
• PIN configuration available for selected requirements
• Insertion loss from 1.3 dB on appropriately specified models
• Defined out-of-band rejection for individual references
• Temperature ranges up to −40 to +105 °C on selected models
• Custom design for application-specific frequency and filtering requirements
• Technical support from EMCO for selection and specification matching

Key features

• Product type: Ceramic Bandpass Filter
• Documented passbands: approximately 0.1052 to 4.900 GHz, depending on reference
• Insertion loss: model dependent
• Rejection: frequency dependent and individually specified for each reference
• Return loss: model dependent
• Temperature range: predominantly −40 to +85 °C; selected models up to +105 °C
• Interfaces: predominantly SMT, with PIN on selected references
• Custom-design parameters: type, frequency band, insertion loss, rejection and isolation

Typical applications

• DAS – Distributed Antenna Systems
• Public Safety
• Radar
• Radio Link
• SatCom
• Wireless
• Frequency-selective RF signal conditioning
• Integration into compact RF and communications assemblies

Additional information

Selection of the appropriate ceramic bandpass filter primarily depends on the required passband, acceptable insertion loss, required rejection, return loss, temperature range and interface.

The power values displayed in the JQL product overview are not associated with an unambiguous unit and have therefore deliberately not been reproduced here.

For requirements not covered by standard references, JQL provides custom design. The manufacturer identifies type, frequency band, insertion loss, rejection and isolation as design parameters.

EMCO Elektronik supports the technical selection of suitable JQL ceramic bandpass filters and the matching of filter characteristics to the relevant RF, communications or system application.
