SKY67180-306LF

RF Amplifiers Overview

The SKY67180-306LF is a two-stage, high-gain low-noise amplifier (LNA) designed for operation within the 1.5 GHz to 3.8 GHz frequency range. It features an ultra-low noise figure of 0.8 dB at 3.5 GHz and provides a typical gain of 31 dB at the same frequency. The device operates on a 5 V supply with a quiescent current of 125 mA. Key linearity metrics include a P1dB compression point of 17 dBm and an OIP3 of 34 dBm. It supports input return loss of 9.5 dB and includes active bias control. The component is rated for temperatures from -40°C to +105°C and is housed in a 16-pin, 4x4 mm QFN package.

RF Amplifiers Procurement Notes

Verify the specific suffix '306LF' to ensure correct packaging and lead-free compliance. Confirm the 16-pin QFN package dimensions match the design footprint. Check RoHS status against current regulatory requirements. Validate the operating temperature range suitability for the target environment. Ensure active bias circuitry compatibility with the system power management design.

RF Amplifiers Selection Notes

Select this LNA when ultra-low noise figure is critical alongside high gain in the 1.5–3.8 GHz range. Consider the 125 mA quiescent current for power budget constraints. Evaluate the 17 dBm P1dB for linearity requirements in dense signal environments. The 4x4 mm QFN package offers a compact solution for space-constrained designs. Verify thermal management capabilities given the +105°C maximum operating temperature rating.
