HMC408LP3

Overview

The HMC408LP3 is a GaAs InGaP HBT MMIC power amplifier designed for the 5.1 GHz to 5.9 GHz frequency range, covering HiperLAN and UNII bands. It delivers a P1dB of 30 dBm with a gain of 20 dB and a noise figure of 6 dB. The device operates on a 5V supply with a current draw of 750 mA. It is housed in a 16-QFN (3x3) surface-mount package with a bare pad.

Feature Summary

• Utilizes GaAs InGaP HBT technology for high efficiency
• Provides +30 dBm output power at 1 dB compression point
• Optimized for HiperLAN and UNII frequency applications

Applications

• HiperLAN wireless communication systems
• UNII band applications
