Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete UPC2762TB-A requires evaluation based on the following critical parameters:

Frequency Coverage: The UPC2762TB-A operates at 2.7GHz ~ 2.9GHz. Substitute parts must support this frequency band or provide broader coverage that encompasses this range.

Gain and P1dB Characteristics: The UPC2762TB-A delivers 11.5dB ~ 17.5dB gain with P1dB of 4.5dBm ~ 7dBm. Substitute parts must meet or exceed these performance specifications to maintain circuit functionality.

Noise Figure: At 7dB ~ 9dB, the noise figure is a critical parameter for receiver-side applications. Substitute parts should not exceed this specification to preserve signal quality.

Supply Voltage and Current: Operating at 2.7V ~ 3.3V with 27mA ~ 35mA current draw, substitute parts must be compatible with existing power supply designs.

Package Compatibility: The 6-pin SOT-363 package is a standard surface mount configuration. Substitute parts in equivalent packages (SC-70-6, 6-VSSOP) are acceptable if pin assignments and electrical characteristics align.

Regulatory Compliance: REACH Unaffected status and EAR99 classification must be maintained in substitute parts.

The HMC311SC70ETR from Analog Devices Inc. is identified as a substitute based on its broader frequency coverage (0Hz ~ 8GHz), superior gain (15dB), improved noise figure (5dB), and active product status with full regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The UPC2762TB-A is obsolete, necessitating substitution for new designs or system maintenance. The HMC311SC70ETR is an active product with full manufacturing support and availability.

Regulatory Compliance: Both parts maintain REACH Unaffected status and EAR99 classification. The HMC311SC70ETR additionally carries ROHS3 compliance, meeting current environmental standards.

Frequency Coverage: The HMC311SC70ETR's 0Hz ~ 8GHz range fully encompasses the UPC2762TB-A's 2.7GHz ~ 2.9GHz operating band, ensuring compatibility for cellular, GPS, and PCS applications.

Performance Characteristics: The HMC311SC70ETR exceeds the UPC2762TB-A specifications in P1dB (11dBm vs. 4.5dBm ~ 7dBm) and noise figure (5dB vs. 7dB ~ 9dB), providing improved signal handling and reduced noise contribution.

Power Supply Considerations: The HMC311SC70ETR requires 5V supply voltage compared to the UPC2762TB-A's 2.7V ~ 3.3V range. Circuit redesign of power distribution may be necessary. Supply current increases from 27mA ~ 35mA to 74mA, requiring thermal and power budget evaluation.

Package Compatibility: Both parts use 6-pin surface mount packages (SOT-363 family). Physical footprint compatibility exists, though pin assignment verification is required during layout design.

Frequently Asked Questions (FAQ)

Q: Can the HMC311SC70ETR directly replace the UPC2762TB-A without circuit modifications?

A: Physical package compatibility exists (both are 6-pin SOT-363 variants), but supply voltage differs significantly (5V vs. 2.7V ~ 3.3V). Power supply circuit redesign is required. Pin assignment verification against schematic documentation is mandatory before implementation.

Q: What are the key performance advantages of the HMC311SC70ETR substitute?

A: The HMC311SC70ETR provides superior P1dB performance (11dBm vs. 4.5dBm ~ 7dBm maximum), lower noise figure (5dB vs. 7dB ~ 9dB), and broader frequency coverage (0Hz ~ 8GHz vs. 2.7GHz ~ 2.9GHz). These characteristics enable improved signal quality and expanded application flexibility.

Q: Are there supply current implications when substituting to the HMC311SC70ETR?

A: Yes. Supply current increases from 27mA ~ 35mA to 74mA. Power budget calculations and thermal management assessment are required to ensure adequate power delivery and component cooling in the target application.

Q: Does the HMC311SC70ETR maintain the same regulatory compliance as the UPC2762TB-A?

A: Both parts are REACH Unaffected and EAR99 classified. The HMC311SC70ETR additionally carries ROHS3 compliance, meeting current environmental and hazardous substance restrictions.

Q: What is the frequency test point difference between these parts?

A: The UPC2762TB-A is tested at 1.9GHz, while the HMC311SC70ETR is tested at 6GHz ~ 8GHz. Both parts operate across their specified frequency ranges, but performance data is characterized at these respective test frequencies.

Q: Is the HMC311SC70ETR suitable for GPS and PCS applications originally designed for the UPC2762TB-A?

A: The HMC311SC70ETR is classified as general-purpose RF amplifier with 0Hz ~ 8GHz coverage, which encompasses GPS (2.4GHz ~ 2.5GHz) and PCS (1.85GHz ~ 1.99GHz) bands. Application suitability requires verification of gain, noise figure, and impedance matching requirements specific to the original circuit design.
