CHR2411-QDG 22-24.5GHz RX Multifunction GaAs Monolithic Microwave IC in SMD leadless package Description The CHR2411-QDG is a monolithic multifunction in K-Band which integrates a low noise amplifier and a mixer generating an IF signal from DC to 1MHz. All the active devices are self biased on chip. The circuit is manufactured with a standard GaAs pHEMT process, 0.25µm gate length, via holes through the substrate, air bridges and electron beam gate lithography. It is available in a 24 leads RoHS compliant QFN4x4 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 guarantee that Tcase remains below 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 cannot be maintained below the maximum temperature specified (see the curve Pdiss. Max) in order to guarantee the nominal device life time (MTTF). Ref. : CHR2411-QDG3116 - 26 Apr 13 3/10 Specifications subject to change without notice Bât.
