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 linear power amplifier's low power consumption and excellent linearity are the result of Fairchild's proprietary InGaP heterojunction bipolar transistor (HBT) technology.
The high-performance RMPA2453 power amplifier internally matches both the input and output to 50ohm, and provides an on-chip power-sensing detector with dual power-saving shutdown options.
"The RMPA4253's superior linearity is evidenced by its 2.5% EVM performance-one of the industry's best within the 802.11 b/g band", said Russ Wagner, General Manager of Fairchild's RF Power Products Group.
"Fairchild is shipping high volumes of this device due to its superior EVM, low power consumption and matched PA module".
According to Boston-based Strategy Analytics, a global research and consulting firm, the WLAN chipset market is expected to reach $757 million in 2004, with unit shipments showing a compound annual growth rate of 32%.
Key features and specifications of the RMPA2453 linear power amp include: 2.5% EVM at 18dBm output provides superior linearity; matched PA module operating with 3.3 V single supply minimises the need for peripheral components, reducing overall BOM costs; two power-saving shutdown options (bias and logic control) minimise power consumption while maintaining performance; an integrated power detector with 20dB dynamic range reduces BOM; and the unit is ideal for use in WLAN routers, access points and adapter cards, and USB dongles.
Fairchild offers an extensive portfolio of high-volume components for the wireless communications industry, including HBT and pHEMT GaAs MMICs, transmit and receive modules and components for handsets, WLAN systems, wireless basestations, datacommunications systems and millimetre-wave systems.
