RFPP3870

RF Amplifiers Overview

The Qorvo RFPP3870 is a hybrid push-pull amplifier module designed for operation within the 45 MHz to 1.218 GHz frequency range. It integrates GaAs MESFET, GaAs pHEMT, and GaN HEMT die technologies to deliver high-performance signal amplification. The device operates on a 24 V supply with a typical current consumption of 260 mA. Key electrical specifications include a gain of 28.5 dB and a noise figure of 4.6 dB. It utilizes an SOT-115J-9 package and supports screw mounting, functioning reliably across temperatures from -30°C to +100°C.

RF Amplifiers Procurement Notes

Verify the specific ordering suffix against official Qorvo documentation to ensure correct pinout and thermal characteristics. Confirm that the SOT-115J-9 package variant matches your chassis mounting requirements. Cross-reference the datasheet revision date to validate the stated 28.5 dB gain and 4.6 dB noise figure parameters for your specific production batch.

RF Amplifiers Selection Notes

Select this component when broadband coverage up to 1.218 GHz is required alongside low noise performance. The hybrid technology integration offers a balance of linearity and efficiency suitable for CATV applications. Ensure the design accommodates the 24 V operating voltage and 260 mA supply current constraints while providing adequate thermal management for the screw-mount package.

RF Amplifiers Part Context

The RFPP3870 belongs to Qorvo's RFPP series of hybrid amplifier modules. This series targets cable television and broadband infrastructure markets. The part leverages mixed semiconductor technologies to optimize performance across wide frequency bands, distinguishing it from single-technology discrete amplifiers.

RF Amplifiers Replacement Considerations

The RFPP2590 is a related Qorvo model in the same series but features different gain and noise specifications. Verify if the lower gain of the alternative meets system requirements before substitution.
