RF Diode Procurement Notes
Verify the specific suffix TR1G to confirm tape and reel packaging configuration. Ensure compatibility with RoHS compliance requirements if operating in regulated regions. Check for obsolescence status as Broadcom has issued notifications for related HSMP-481B variants, which may impact long-term supply availability for this QSMP variant.
RF Diode Selection Notes
Select this component when low capacitance and controlled series resistance are critical for RF performance. Consider the 50 V reverse voltage rating for circuit biasing conditions. Evaluate the surface-mount package type against PCB layout constraints and assembly capabilities. Confirm that the PIN diode characteristics align with the required attenuation range and frequency specifications of the target application.
RF Diode Part Context
This part belongs to Broadcom's portfolio of RF diodes and attenuators. It is functionally related to the HSMP-481B series, though distinct in packaging or specific electrical parameters. Broadcom Limited provides these components for use in communication equipment and RF subsystems requiring precise signal control.
RF Diode Replacement Considerations
Broadcom has announced obsolescence for the HSMP-481B-TR1G. While QSMP-481B-TR1G is listed separately, verify if it shares the same end-of-life status. Consult official Broadcom documentation for direct substitute part numbers before redesigning.
