MC1496BD

Overview

The MC1496BD is a balanced modulator and demodulator integrated circuit manufactured by onsemi. It operates within a frequency range of 80 MHz to 300 MHz, suitable for FM applications. The device functions as an analog multiplier where the output voltage represents the product of an input signal voltage and a switching carrier function. It is housed in a 14-SOIC surface-mount package with a width of 3.90 mm. Key electrical specifications include a maximum supply current of 5 mA and a maximum operating temperature of 125°C. The component supports balanced modulation formats and is designed for high-frequency RF signal processing tasks.

Feature Summary

• Provides balanced modulation and demodulation capabilities for RF signals
• Functions as an analog multiplier producing output proportional to signal and carrier inputs
• Supports operation up to 300 MHz for FM application integration

Applications

• FM transmitter and receiver circuits
• RF signal mixing and frequency conversion stages
• Balanced modulator implementations in communication systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as historical data indicates potential non-compliance for older batches. Check datasheet revisions for pinout consistency. Ensure storage conditions meet moisture sensitivity level requirements prior to assembly. Validate that the specific lot number matches the requested manufacturing date code to avoid obsolete stock issues.

Selection Notes

Select this component when a dedicated balanced modulator/demodulator is required for frequencies between 80 MHz and 300 MHz. Consider the 14-SOIC package constraints for PCB layout space. Evaluate power consumption limits against system thermal design, noting the 5 mA supply current specification. Ensure the application requires analog multiplication functionality rather than digital switching. Verify compatibility with existing carrier signal amplitudes and input impedance requirements.

Part Context

The MC1496BD belongs to the MC1496 series of balanced modulators/demodulators from onsemi. This family is widely recognized for its use in analog communication circuits requiring precise signal mixing. The BD suffix typically denotes a specific temperature grade or packaging variant within the broader MC1496 product line. It serves as a foundational component for designing efficient RF front-ends and intermediate frequency stages in legacy and specialized radio equipment.

Replacement Considerations

Direct substitutes include the MC1496BDR2G and MC1496DR2G from onsemi. These variants offer updated manufacturing processes and potentially different environmental compliance statuses. Verify pin-to-pin compatibility and electrical parameter equivalence before substitution. Review official replacement guides for any functional differences in recommended operating conditions.
