RF Demodulator IC F1370NBGI Equivalent & Substitute Parts

Part Overview

The F1370NBGI is an RF Demodulator IC manufactured by Renesas Electronics Corporation, designed for RF signal demodulation across the 1.45GHz to 2.7GHz frequency range. This component operates with a 5V supply and delivers 12dB gain with a 17dB noise figure in a 36-pin WFQFN surface mount package. The product is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the F1370NBGI are identified based on functional demodulation capability and electrical parameter compatibility. The primary substitution criteria include RF frequency range overlap, LO frequency range compatibility, supply voltage compatibility, and surface mount package availability. The F1350NBGI represents a direct manufacturer alternative from Renesas Electronics Corporation. The AD8339ACPZ and AD8348ARUZ-REEL7 represent cross-manufacturer alternatives from Analog Devices Inc., each with distinct frequency band coverage and electrical characteristics.

Substitution logic is determined by:

• RF frequency range coverage relative to the 1.45GHz ~ 2.7GHz requirement
• LO frequency range compatibility with the 1.4GHz ~ 2.9GHz specification
• Supply voltage compatibility with 5V operation
• Surface mount package configuration
• Active product status and compliance certifications

Parameter Comparison

Engineering Selection Recommendations

F1350NBGI (Renesas Electronics Corporation): This part represents the manufacturer-recommended direct substitute. As an active product from the same manufacturer, it maintains design continuity and supply chain alignment. Detailed electrical specifications are not provided in available documentation; direct consultation with Renesas Electronics Corporation is required to confirm parameter compatibility with the F1370NBGI application requirements.

AD8339ACPZ (Analog Devices Inc.): This RF demodulator operates in the 0Hz to 50MHz RF frequency range with LO frequency capability to 200MHz. The frequency band does not overlap with the F1370NBGI's 1.45GHz to 2.7GHz specification. This part is suitable only for applications requiring lower frequency demodulation. MSL rating of 3 requires controlled moisture exposure during storage and handling.

AD8348ARUZ-REEL7 (Analog Devices Inc.): This RF demodulator covers 50MHz to 1GHz RF frequency range with LO frequency to 2GHz. The RF frequency range does not extend to the 1.45GHz to 2.7GHz requirement of the F1370NBGI. This part is applicable for applications in the 50MHz to 1GHz band. Supply voltage range of 2.7V to 5.5V provides flexibility for lower voltage systems. MSL rating of 1 permits unlimited moisture exposure.

All substitute candidates maintain ROHS3 compliance and REACH unaffected status, consistent with the main part specifications.

Frequently Asked Questions (FAQ)

Q: Can the F1350NBGI directly replace the F1370NBGI in existing designs?

A: The F1350NBGI is the manufacturer-recommended substitute from Renesas Electronics Corporation. However, complete electrical parameter specifications for the F1350NBGI are not provided in available documentation. Verification of RF frequency range, LO frequency range, gain, noise figure, and P1dB characteristics against your specific application requirements is necessary before implementation.

Q: Why are the Analog Devices parts (AD8339ACPZ and AD8348ARUZ-REEL7) listed as substitutes if their frequency ranges do not match?

A: These parts are listed based on the manufacturer's substitute list provided for the F1370NBGI. The AD8339ACPZ operates at 0Hz to 50MHz and the AD8348ARUZ-REEL7 operates at 50MHz to 1GHz. Neither part covers the 1.45GHz to 2.7GHz RF frequency range of the F1370NBGI. These parts are suitable only for applications with different frequency requirements.

Q: What are the package differences between substitute parts?

A: The F1370NBGI uses a 36-pin WFQFN package (6x6mm). The F1350NBGI uses a VFQFPN package (6.00x6.00x0.80mm). The AD8339ACPZ uses a 40-pin VFQFN CSP package (6x6mm). The AD8348ARUZ-REEL7 uses a 28-pin TSSOP package (0.173" width, 4.40mm). PCB layout modifications are required when transitioning between different package types.

Q: What is the significance of MSL ratings for these parts?

A: MSL (Moisture Sensitivity Level) indicates moisture exposure limits during storage and handling. The F1370NBGI, F1350NBGI, and AD8348ARUZ-REEL7 have MSL 1 rating, permitting unlimited moisture exposure. The AD8339ACPZ has MSL 3 rating, requiring controlled moisture exposure not exceeding 168 hours at specified conditions before soldering. MSL 3 components require desiccant storage and baking procedures prior to assembly.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The F1370NBGI, F1350NBGI, AD8339ACPZ, and AD8348ARUZ-REEL7 are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What supply voltage considerations apply to substitute selection?

A: The F1370NBGI operates at 5V. The F1350NBGI specifications are not provided. The AD8339ACPZ operates at 4.5V to 5.5V, compatible with 5V systems. The AD8348ARUZ-REEL7 operates at 2.7V to 5.5V, providing broader voltage flexibility. Verify supply voltage compatibility with your system design before part selection.
