UHF RF power transistor supports DVB-T digital broadcast transmitters
September 23, 2010 // Paul Buckley
NXP Semiconductors N.V., has unveiled an Ultra High Frequency (UHF) RF power transistor which is a 600 W LDMOS device for broadcast transmitters and industrial applications.
NXP claims the BLF888A is the most powerful LDMOS broadcast transistor in the market to date. For a DVB-T signal over the full UHF band from 470 to 860 MHz, the transistor can deliver 120 W average power with efficiencies greater than 31 percent. Featuring excellent linearity, high gain of 21 dB and outstanding ruggedness corresponding to VSWR greater than 40:1, the BLF888A is ideal for advanced digital transmitter applications, such as DVB-T.
The performance of the BLF888A is enabled by NXP’s 50 V high voltage LDMOS process technology in combination with advanced thermal concepts, resulting in unprecedented power density and thermal resistance as low as 0.15 K/W. As a consequence, the BLF888A allows broadcast equipment manufacturers to optimize existing or new transmitter installations for performance and total cost of ownership. For complete power amplifier line-ups, the BLF888A combines optimally with the BLF881 driver transistor.
The new transistor is available in two versions: a bolt-down package - BLF888A and an earless package - BLF888AS, which enables a more compact PCB design. The BLF888AS can be soldered to achieve a further decrease in junction temperature.
With more than 4 billion RF products shipped annually, NXP is an industry leader in High Performance RF. NXP’s leading LDMOS technologies together with advanced package concepts enables best-in-class RF power transistor performance, featuring high power and outstanding ruggedness for all broadcast technologies.
The BLF888A will be showcased at the European Microwave Week, NXP Booth No. 194, from September 26 - October 1, 2010 in Paris.
The BLF888A and BLF888AS are sampling now.
