Ampleon announced the availability of the BLCU188XRS, a 1400W, CW capable, high power extremely rugged transistor constructed in a thermally optimized air cavity ACP3 copper flanged plastic package. Able to withstand extremely load mismatches, up to a VSWR > 65:1, this Gen6 HV 50 V LDMOS device has a 30 percent better thermal resistance (R,th) compared to a traditional air cavity ceramic packaged transistor, and combined with its high efficiency, requires less stringent cooling requirements.
