SKY67110-396LF

RF Amplifiers Overview

The SKY67110-396LF is a high linearity, active bias Low-Noise Amplifier (LNA) designed for the 300 MHz to 750 MHz frequency range. Manufactured using GaAs pHEMT technology, it operates on a 5 V supply with a current draw of 76 mA. Key electrical specifications include a gain of 21 dB and a noise figure of 0.65 dB at 450 MHz. The device provides a 1 dB compression point (P1dB) of 1 dBm and an output third-order intercept point (OIP3) of 37 dBm. It features an input return loss of 17.5 dB and isolation of 28 dB. The component is housed in a compact DFN-8 surface-mount package and supports an operating temperature range from -40°C to +105°C.

RF Amplifiers Procurement Notes

Verify the specific revision status and RoHS compliance details directly with Skyworks Solutions or authorized distributors before procurement. Confirm that the DFN-8 package handling procedures align with your manufacturing capabilities. Ensure that the active bias requirements are supported by your system power design. Cross-reference the datasheet version to confirm pinout and electrical characteristics match your schematic requirements.

RF Amplifiers Selection Notes

Select this component when designing sub-GHz receiver chains requiring high linearity and low noise. The 5 V supply requirement suits infrastructure equipment more than battery-operated portable devices. Compare the 21 dB gain against system link budget needs. Evaluate the P1dB and OIP3 values to ensure adequate dynamic range for your specific interference environment. Consider the DFN-8 footprint for PCB space constraints.

RF Amplifiers Part Context

The SKY67110-396LF belongs to Skyworks' portfolio of ultra-low-noise amplifiers covering frequencies from 50 MHz to 3.8 GHz. It shares the common 2x2 mm DFN package form factor with other family members like the SKY67150 series. This standardization simplifies layout and board design across different frequency bands. The device complements higher frequency LNAs and discrete FETs in comprehensive RF front-end solutions.
