Dual-band power amp boosts 3G efficiency
The PowerEdge dual-band WCDMA/UMTS RF power amplifier module boasts a power-added efficiency of 42% - claimed as a significant improvement over competing offerings.
Fairchild Semiconductor's PowerEdge dual-band WCDMA/UMTS RF power amplifier module (PAM) increases power-added efficiency (PAE) to 42%, a significant improvement over competing offerings As the first 3G PAM to offer both 1850-1910 and 1920-1980MHz operation in a 3 x 3mm LCC package, Fairchild's RMPA2265 is approximately 44% smaller than alternative 4 x 4mm packages

Dual-output buffer for DDR SDRAM modules
Fairchild Semiconductor has introduced a dual-output registered buffer for 184-pin, 2.5V PC200/PC266, 72bit-wide registered double data rate (DDR) SDRAM modules.
Bus hold makes logic more predictable
Fairchild Semiconductor has made a number of additions to its LCX family, the logic industry standard for 3.3V applications.
The RMPA2265 addresses the high efficiency, frequency flexibility and size requirements of today's 3G mobile handsets, PDAs and wireless PC data cards.
The RMPA2265 is also compliant with the emerging High-Speed Downlink Packet Access (HSDPA) standard.
"Fairchild's PowerEdge dual-band PAMs enable OEMs to design products, allowing customers to access greater frequency band options and significantly extend the range of coverage", says Russ Wagner, General Manager of Fairchild's RF power products group.
"With increasingly converging functions in cellphones, and the need for power efficiency, the RMPA2265 offers advantages in reducing board space, extending talk time and dual-band frequency flexibility in the industry's smallest package".
The RMPA2265's excellent linearity and high power-added efficiency are achieved through Fairchild's proprietary InGaP heterojunction bipolar transistor (HBT) technology.
The device has selectable high/low power modes used to further optimise current consumption.
The two-stage power amplifier internally matches both the input and output to 50ohm to minimise the use of external components, thus simplifying design requirements.
The lead (Pb)-free RMPA2265 meets or exceeds the requirements of the joint IPC/JEDEC standard J-STD-020B and is compliant with European Union requirements now in effect.
