The CHA1452-QDG is a three-stage GaAs Low Noise Amplifier operating in the 30 – 44GHz frequency band including current regulation circuit on each stage. This LNA typically presents low Noise Figure of 1.75dB associated to a small signal Gain of 20dB.
It can provide up to 4dBm output power at 1dB gain compression and needs DC power supply of Vdd=3V and Vss=-3V corresponding to a current of 47mA. The current variation is lower than 2mA when the temperature varies from -40°C to 85°C thanks to the integrated regulation on each stage of the LNA. It is available in 4x4 plastic package.
Designed for space applications, it is also ideal for a wide range of microwave systems.
This new product is developed using GaAs pHEMT process and is provided on low cost SMD RoHS compliant QFN plastic package.
