RF Micro Devices (RFMD) Inc. launches RFHA1000 GaN power IC, a wideband power amplifier that features operation of 28V and output power of 15W and claims to deliver 50-1000MHz instantaneous bandwidth and 17dB gain.


The RFHA1000 is designed for continuous wave and pulsed applications.

The RFHA1000 aims for continuous wave and pulsed applications. These include military communications, electronic warfare, wireless infrastructure, radar, two-way radios and general purpose amplification. According to the company, the device achieves high efficiency, flat gain and power over a large instantaneous bandwidth.

The discrete amplifier is 50Ω input-matched, and packaged in a small form factor 5 x 6mm SOIC-8 outline air cavity ceramic package that provides excellent thermal stability through the use of advanced heat sink and power dissipation technologies. Ease of integration is accomplished through the incorporation of an optimised input matching network within the package that provides wideband gain and power performance in a single amplifier. An external output match offers the flexibility of further optimising power and efficiency for any sub-band within the overall bandwidth, the company noted.

The RFHA1000 claims a power added efficiency of 60 per cent and offers EAR99 export control. Large-signal models are available for the device.
