Key Parameters

Substitute Part Grouping Explanation

Substitution of the BLC8G27LS-60AVH is determined by alignment across the following critical parameters:

Frequency Compatibility: The substitute part must operate within or encompass the 2.3GHz to 2.69GHz band of the original device.

Supply Voltage: The substitute must support 28V operation, matching the test voltage specification of the main part.

Gain Performance: The substitute gain specification must be documented and suitable for RF amplification applications.

Manufacturer Continuity: Ampleon USA Inc. maintains product lineage and technical compatibility across its RF transistor portfolio.

Product Status: Active status ensures availability and ongoing technical support, addressing the obsolescence of the original part.

The BLM9D2327S-50PB meets these substitution criteria through frequency band overlap (2.3GHz to 2.7GHz), 28V supply voltage alignment, and active product status from the same manufacturer.

Parameter Comparison

Engineering Selection Recommendations

The BLM9D2327S-50PB is an active substitute for the obsolete BLC8G27LS-60AVH based on the following engineering criteria:

Frequency Band Alignment: Both parts operate within the 2.3GHz to 2.7GHz range, with the substitute covering the primary operational band of the original device.

Supply Voltage Compatibility: Both devices are specified for 28V operation, ensuring direct voltage compatibility in existing circuit designs.

Manufacturer Continuity: Both parts are manufactured by Ampleon USA Inc., ensuring consistent design philosophy and technical support infrastructure.

Product Availability: The substitute part holds active product status with documented inventory, addressing the procurement challenges associated with the obsolete main part.

Compliance Status: The substitute part is ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic component procurement.

The gain differential (27.5dB versus 15dB) represents a performance enhancement and must be evaluated within the context of the specific circuit application to ensure compatibility with downstream components and system-level gain budgets.

Frequently Asked Questions (FAQ)

Q: Can the BLM9D2327S-50PB directly replace the BLC8G27LS-60AVH in existing designs?

A: Direct replacement requires circuit-level evaluation. Both parts operate at 28V and cover the 2.3GHz to 2.7GHz frequency band. The substitute exhibits higher gain (27.5dB versus 15dB), which may require adjustment of matching networks and bias circuitry to maintain system stability and performance specifications.

Q: What is the primary reason for substitution?

A: The BLC8G27LS-60AVH is classified as obsolete, limiting procurement availability. The BLM9D2327S-50PB is an active product from the same manufacturer, ensuring continued supply and technical support.

Q: Are the package types compatible?

A: The main part uses SOT-1275-1 (DFM6) packaging, while the substitute uses OMP-780-16F-1 packaging. These are different physical packages and require PCB layout modifications for implementation.

Q: What compliance certifications apply to the substitute part?

A: The BLM9D2327S-50PB is ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards for electronic component procurement.

Q: How does the gain difference affect system performance?

A: The substitute part provides 12.5dB additional gain compared to the original device. System designers must verify that this gain increase does not cause instability, excessive output power, or non-linear distortion in the target application.

Q: Is the frequency range difference significant?

A: The substitute covers 2.3GHz to 2.7GHz, while the original covers 2.3GHz to 2.69GHz. The 10MHz difference at the upper frequency limit is negligible for most applications within this band.
