UHF transistor boosts power for
broadcast
World's first true 300W ultra-high-frequency transistor is designed for the TV transmitter/broadcast market.
NXP describes its BLF878 as the world's first true 300W ultra-high-frequency (UHF) transistor Based on the company's high voltage Generation 6 LDMOS process, the new power transistor is targeted at the TV transmitter/broadcast market

High security for smart card MCU family
Philips Semiconductors describes SmartMX as the world's first ultra-low-power cost-optimised high-performance family of smart card controller ICs.
The industry is now trending towards increased output power to accommodate high-definition TV, with NXP's latest solution delivering unparalleled efficiency levels, broadcasters are able to significantly increase output power and lower capital expenditure at the same time.
Today's high-performance TV transmitters constitute serious investments, and broadcasters rightly seek to use the maximum power available in order to transmit the huge amounts of data necessary to beam DVB-T and DVB-H (digital video broadcasting) programming to our homes.
The BLF878 UHF power LDMOS transistor enables this, maximising power output from available input and increasing efficiency to 55% constant wave (CW) and 32% for digital broadcasting - leading to huge cost savings for broadcasters.

Philips Semiconductors has released the SAA7115 9bit video decoder, with high-performance comb filter, enhanced Macrovision detection and advanced VBI data slicing capability.
As no other competing product is capable of supporting the entire UHF band at 300W at the same performance, by using NXP's new solution, broadcasters can employ fewer components than previously needed to deliver this level of power, resulting in further savings.
"Manufacturers of broadcast equipment are under increasing pressure to deliver richer content to our screens, putting greater strain on transmitters with costs often spiralling out of control".
"Although our input is perhaps the smallest in actual size, the difference made to the bottom line is significant when you consider the expenditure involved", claims Guido Bekkers, Worldwide Marketing Manager, RF Power Broadcast and Microwave, NXP Semiconductors.
"By being the first to market with such a powerful solution, we have consolidated our position as the number one in the market, delivering yet another efficient, powerful and cost-effective solution to our growing customer base".
NXP is the recognised leader in the worldwide UHF broadcast market.
The BLF861A, its flagship product, was launched in late 2000 and has become the de facto industry standard.
Current customers include the top five TV broadcast manufacturers.
The BLF878 UHF power LDMOS transistor is a highly robust solution, capable of withstanding the rigours of high-performance broadcast operations with a VSWR (voltage standing wave ratio) of 10:1.
NXP is also to introduce a new family of 50V high voltage LDMOS transistors in the fourth quarter of 2007 aimed at the ISM (industrial, scientific and medical) market.
The BLF878 UHF power LDMOS transistor will be sampling to selected customers in the third quarter of this year and will be ramping up in Q4 2007.
