Question: Is it possible to use the ADMV4530 in the 27.5–31 GHz frequency band in IF mode, even if this results in reduced performance? Customer's intended configuration: Operating mode: IF mode IF input: 2 GHz (L-band) VCO frequency: 14.5 GHz RF output: 31 GHz Can this configuration operate as intended? If so, is any degradation in performance expected, and if applicable, what specific performance metrics might be impacted? Answer: The ADMV4530 is designed to operate in the 24 GHz to 30.5 GHz frequency range, so using it at 31 GHz is slightly outside its specified range. However, it may still function with some performance degradation. Regarding the customer's setup: IF input of 2 GHz and VCO at 14.5 GHz should result in an RF output of 31 GHz, which is slightly above the upper limit of the ADMV4530's specified range. Performance Reduction: Operating at 31 GHz may lead to reduced gain, increased phase noise, and possible degradation in linearity. The conversion loss may also be higher, and the device's filtering characteristics may not be optimal for this frequency. Recommendation: Testing with an evaluation board is advisable to assess performance in this specific configuration. If strict performance requirements exist, an alternative mixer covering a wider frequency range should be considered.
