CER0137A

Overview

The CER0137A is a ceramic bandpass filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It operates with a center frequency of 1.96 GHz and provides a bandwidth of 60 MHz. The device features an insertion loss of less than 1.8 dB. Designed for surface mount installation, it utilizes a monoblock package with two PCB pads. The component is RoHS compliant and classified under ECCN EAR99.

Feature Summary

• Provides signal conditioning through bandpass filtering in the 1.93 to 1.99 GHz range
• Utilizes a monoblock construction for compact surface mount integration
• Ensures electromagnetic compatibility within specified operational frequencies

Applications

• Wireless communication systems operating in the 1.9 GHz spectrum
• Signal conditioning circuits requiring narrowband filtering
• Electromagnetic compatibility (EMC) applications

Procurement Notes

Verify the specific datasheet version for the CER0137A to confirm exact electrical tolerances and mechanical dimensions prior to integration. Ensure that the surface mount pad layout matches the manufacturer's recommended footprint to guarantee reliable soldering and performance. Confirm RoHS compliance status if required by specific regulatory standards for the target assembly.

Selection Notes

Select the CER0137A when a fixed center frequency of 1.96 GHz with a 60 MHz bandwidth is required. Consider this component for designs prioritizing low insertion loss and compact monoblock packaging over tunable alternatives. Evaluate the surface mount form factor against available board space constraints and thermal management requirements for the specific application environment.
