Description

The CHA3801-QDG is an L -Band LNA monolithic circuit including an active bias network. Furthermore a protection network is included in order to allow high input power survivability. It is designed for a wide range of applications, from military to commercial communication systems. The circuit is man ufactured with a pHEMT process, 0.25µm gate length, via holes through the substrate, air bridges and electron beam gate lithography. It is supplied in RoHS compliant SMD package.

The temperature is monitored at the package back-side interface (Tcase) as shown below. The system maximum temperature must be adjusted in order to gu arantee that Tcase remains below than the maximum value specified in the next table. So, the system PCB must be designed to comply with this requirement. A derating must be applied on the dissipated power if the Tcase temperature can not be maintained below than the maximum temperature specified (see the curve Pdiss. Max) in order to guarantee the nominal device life time (MTTF).
