Procurement Notes
Verify RoHS compliance status through official manufacturer documentation prior to procurement. Confirm current availability as the product may be subject to factory special order requirements. Ensure that the specific ordering suffix matches the required reel packaging quantity and termination specifications. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and supply chain integrity before finalizing purchase orders.
Selection Notes
Select this component when a dedicated SAW duplexer is required for the 1.85-1.91 GHz frequency range. Consider the 2.6 dB insertion loss specification for link budget calculations. Verify that the 23.93 mm x 6.55 mm footprint fits the PCB layout constraints. Ensure the operating temperature range of -40 C to +85 C aligns with the environmental conditions of the target application system.
