SPA-120-41-01-SMA

RF Amplifiers Overview

The SPA-120-41-01-SMA is a medium power GaAs amplifier manufactured by Fairview Microwave, designed for the X-band frequency range of 8 GHz to 12 GHz. It delivers a gain of 41 dB with a saturated output power (Psat) of 1 Watt. The device features SMA input and output connectors and operates on a single DC supply voltage. Key performance metrics include a minimum P1dB compression point of 30 dBm and an Output Third-Order Intercept Point (OIP3) of 41 dBm. This coaxial power amplifier is suitable for applications requiring high gain and stable performance within its specified bandwidth.

RF Amplifiers Procurement Notes

Verify the specific datasheet version for the SPA-120-41-01-SMA to confirm current electrical tolerances and mechanical dimensions. Ensure that the system power supply matches the required voltage and current specifications for optimal performance. Confirm connector compatibility and impedance matching before integration. Check for any recent updates regarding RoHS compliance or manufacturing changes directly from Fairview Microwave documentation.

RF Amplifiers Selection Notes

Select this component when a high-gain, medium-power solution is needed specifically for the 8 to 12 GHz range. The 41 dB gain distinguishes it from lower-gain variants in the SPA series. Consider the 1 Watt Psat limit when designing for linearity requirements. The SMA interface simplifies prototyping compared to flanged connectors. Evaluate thermal management needs based on the power dissipation at full saturation.

RF Amplifiers Part Context

This model belongs to Fairview Microwave's SPA series of medium power amplifiers. These components are engineered for general-purpose RF applications where consistent gain and power output are critical. The series typically offers various gain and frequency options, with this specific part targeting the X-band market segment using GaAs semiconductor technology for efficiency and performance.

RF Amplifiers Replacement Considerations

Direct substitutes may include other Fairview Microwave models within the SPA series with similar gain and frequency ranges, such as the SPA-110-30-01-SMA, though frequency bands differ. Cross-manufacturer replacements require careful verification of pinout, biasing requirements, and S-parameter performance to ensure system compatibility without redesign.
