UHF power LDMOS transistor

The BLU9H0408L-800P is an 800 W LDMOS power transistor for UHF radar applications operating between 400 to 800 MHz and has an efficiency of 67%, integrated dual-sided ESD protection, is extremely rugged and delivers gain of 20.5 dB. The operating voltage is 65 VDC and the unit is mounted in a flanged balanced ceramic package. The BLU9H0408L-800P can withstand a load mismatch VSWR of 20:1 through all phases under the following conditions: VDS = 50 V. It is designed to meet the requirements for radar applications, and as LDMOS is inherently rugged the device can tolerate conditions that are typical in radars, such as frequent changes in temperature, voltage, and other operating conditions.
