HMC341LC3B

Overview

The HMC341LC3B is a GaAs pHEMT MMIC Low Noise Amplifier housed in a leadless RoHS compliant SMT package. Operating from 21 to 29 GHz, the amplifier provides 13 dB gain and 2.5 dB noise figure. It operates from a single +3V supply with a current of 35 mA. The device features DC-blocked RF I/Os matched to 50 ohms, requiring no external components. Key electrical specifications include a P1dB of 8.5 dBm, an input return loss of 10 dB, and an output return loss of 14 dB. The package is a 12-VFQFN exposed pad (3x3 mm).

Feature Summary

• Requires no external matching components due to integrated 50-ohm impedance matching.
• Operates on a single +3V power supply for simplified circuit design.
• Housed in a leadless, RoHS-compliant surface-mount package.

Applications

• Point-to-point radio systems
• Point-to-multipoint radio systems
• VSAT applications
• Test equipment and sensors
• Military terminal applications

Procurement Notes

Verify the specific ordering suffix to ensure the correct packaging type, such as tape and reel or cut tape, matches the assembly requirements. Confirm that the component meets the required RoHS3 compliance standards for environmental regulations. Check the moisture sensitivity level (MSL 3) and storage conditions to prevent damage before soldering. Ensure the supplier provides valid documentation confirming the part is from Analog Devices Inc. and not a generic substitute.

Selection Notes

Select this component when designing circuits for the 21 to 29 GHz frequency range requiring low noise amplification. Consider the 13 dB gain and 2.5 dB noise figure for signal integrity in high-frequency paths. The single-supply operation simplifies power management compared to dual-supply alternatives. Evaluate the thermal resistance and power dissipation limits if operating in high-temperature environments or dense PCB layouts.
