Description
The Filtronic LMA208C is a medium power PHEMT amplifier that operates from 2 to 26GHz. This 5-stage travelling wave amplifier provides
10dB nominal gain and 1-dB gain compression power output of greater than 19dBm. The LMA208C is designed for use as wideband driver
amplifer in ECM (Electronic Counter-Measure) and commercial communication system applications. Ground is provided to the circuitry
through vias to the backside metallization.
