About RF Attenuators

RF attenuators are passive components that reduce signal power without distorting waveform integrity. They prevent receiver overload, improve impedance matching, and enable precise signal level control in high-frequency circuits. Proper attenuation is crucial for optimizing SNR (Signal-to-Noise Ratio) and preventing damage to sensitive downstream components.

Fixed attenuators like the ALM-38140-BLKG provide stable, predetermined loss values ideal for calibrated systems. They serve essential roles in signal path conditioning, test setups, and transmission line stability across 5G infrastructure, military radios, and laboratory instrumentation.

Packaging

Available in Strip packaging for automated assembly compatibility.

FAQs

Q: Is this Broadcom attenuator RoHS compliant?
A: As an obsolete component, compliance depends on manufacturing date. Contact PCX for batch-specific documentation.

Q: Can I use this for 5G prototyping?
A: Yes, its 4GHz frequency range covers sub-6GHz 5G bands. Verify power requirements against your design.

Q: What’s the tolerance on attenuation values?
A: Consult the datasheet for exact specs. Broadcom attenuators typically maintain ±0.5dB consistency.

Q: How do I handle ESD with this component?
A: Always use grounded wrist straps and anti-static mats. The 6-MCOB package is sensitive to electrostatic discharge.

Q: Why choose obsolete RF components?
A: They ensure continuity in legacy systems where redesigns are cost-prohibitive or require requalification.

Q: Does PCX provide samples?
A: Yes, request samples via our portal. Availability depends on stock for obsolete items.
