Frequently Asked Questions
Q1: What is the difference between SA612AD/01, NE612 and SA602?
A: SA612AD/01 is SOIC-8 industrial-grade SMD version. NE612 is available in DIP-8 and SOIC-8 packages. All three models are pin-to-pin compatible with the same core circuit.
Q2: Can external LO signal drive SA612AD/01?
A: Yes. The internal oscillator pin accepts external LO input if the built-in oscillator is not required.
Q3: Why conversion gain shows 14dB and 17dB on different datasheets?
A: Gain varies with frequency and test conditions. 14dB @45MHz is standard reference value; 17dB can be reached under specific operating parameters.
Q4: SA612AD/01 is discontinued, are there compatible alternative ICs?
A: NXP has discontinued this device with limited stock remaining. Contact our sales team for cross-reference recommendations according to your circuit design.
Q5: Can this mixer be applied to HF amateur radio frequency conversion?
A: Yes. Many ham radio designs use the SA612 series for HF/VHF mixing and frequency shifting.
Q6: Is SA612AD/01 identical to SA612AD/118?
A: The die core is exactly the same. Suffix /01 and /118 only represent production batch & packaging rules, electrical specifications are fully consistent.
Q7: How can I get the official datasheet and bulk pricing?
A: Send an inquiry, we will provide datasheet, check real-time stock and offer bulk quotation within 24 hours.
