NXP Semiconductors announced new additions to its ultra high-frequency (UHF) and FM broadcast product portfolio, including the BLF888B transistor.
Configured as a Doherty power amplifier, the BLF888B achieves 50% DVB-T efficiency, offering reductions in the power consumption of UHF broadcast systems.
NXP’s latest UHF and FM LDMOS power transistors offer cost-effective solutions for specific power levels, using thermally optimised transistor designs. Innovations include improved ruggedness over the full UHF frequency band from 470 to 860 MHz, which enables the application to withstand extreme mismatches. Both the BLF888A and BLF888B feature low thermal resistance of 0,15 K/W.
The BLF178P transistor is optimised for FM radio transmitters in terms of cost/performance, delivering 1 kW CW with 75% efficiency at 108 MHz and 26,5 dB gain.
