RA81F1427STGNM#BD0

RF Amplifiers Overview

The RA81F1427STGNM#BD0 is a general-purpose RF driver amplifier manufactured by Renesas Electronics. It operates within a frequency range of 2.3 GHz to 4.2 GHz and requires a supply voltage of 5 V. Key electrical specifications include a gain of 35.5 dB, a P1dB compression point of 28 dBm, and an operating supply current of 145 mA. The device is housed in a 16-VFQFPN (3x3) surface-mount package.

RF Amplifiers Feature Summary

• Provides high linearity amplification suitable for driver stages in wireless communication systems.
• Features differential input and single-ended output configuration for impedance matching flexibility.

RF Amplifiers Applications

• Wireless LAN infrastructure
• Point-to-point microwave radio links
• Broadband wireless access systems

RF Amplifiers Procurement Notes

Verify the specific suffix (#BD0) against the manufacturer's official datasheet to confirm pinout and packaging details. Ensure compatibility with existing PCB layouts designed for the 16-VFQFPN form factor. Confirm that the 5V supply rail meets the required current capacity for the specified operating conditions.

RF Amplifiers Selection Notes

Select this component when a moderate gain stage is required between low-noise amplifiers and power amplifiers. The 35.5 dB gain and 28 dBm output power make it suitable for driving subsequent stages in multi-stage amplifier chains. Consider thermal management requirements due to the 500 mW power dissipation rating during operation.

RF Amplifiers Part Context

This part belongs to the RA81F series of RF amplifiers from Renesas Electronics. It is distinct from other variants such as the RA81F1485 or RA81F1427#KD0, which may differ in frequency range, gain, or packaging. The #BD0 suffix specifically denotes the tray packaging variant.

RF Amplifiers Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Evaluate alternative Renesas models like the RA81F1427STGNM#KD0 for reel packaging needs, but verify electrical parameter equivalence before implementation.
