Many engineers are under pressure to extend battery life in their applications, and these new devices meet that demand by offering high power- added efficiency to reduce battery current drain, while their low operating voltages further extend battery life.
The SST12LP17E’s matched input and output ports are easy to use and enable faster time-to- market. Additionally, this device requires no external RF matching components and requires only one external capacitor, taking up less board space.
“With the release of these new power amps, Microchip can now offer customers the same reliable operation over temperature with even lower operating voltages,” said Daniel Chow, vice president of Microchip’s Radio Frequency Division. “Combined with high-efficiency operation, these low-operating-voltage devices extend the operating battery life for applications in the consumer- electronics industry.”
Packaging, Pricing and Availability
The new RF power amps are available in an 8-pin 2mm x 2mm x .45mm QFN package. The fully matched, low-power SST12LP17E is priced at $0.48 each, in 10,000-unit quantities, while the low- power SST12LP18E is available for $0.29 each, in 10,000-unit quantities. Samples are available today, and volume-production quantities can be ordered today.
Flexible TriQuint broadband LNAs simplify RF design
The firm’s new low noise amplifiers provide flexible, highly-efficient linear solutions for mobile network base stations, repeaters, point-to-point radios, test and other high-performance applications.
Global RF solutions supplier and technology innovator, TriQuint Semiconductor has released four new linear low noise amplifiers (LNAs) that eliminate matching components in a wide range of high-performance broadband applications including 3G/4G base station networks.
TriQuint is focused on bringing performance innovation to essential building blocks in the global network. This network is fraught with demand that continues to grow; according to 2011 Cisco Visual Networking Index, by 2015, the amount of mobile data traffic contributed by tablets alone is expected to equal that of mobile data traffic from all devices combined in 2010.
“Consumer demand for smartphones and tablets means more bandwidth through the network, which leads to the need for greater RF chain linearity”, said Vice President Brian P. Balut. Our customers want to integrate functions for simplified design and greater efficiency. TriQuint solutions deliver by leveraging our unique technology portfolio and experience meeting worldwide network RF design requirements.”
TriQuint’s new low noise amplifiers are part of a wide-ranging portfolio created to provide flexible, highly-efficient linear solutions for broadband markets including mobile network base stations, repeaters, point-to-point radios, test and other high- performance applications.
Available in cost-effective standard surface-mount packages, these cascadable 50 Ω low noise amplifiers consume as little as 50 mA of electrical current and offer a variety of gain options from 15- 19 dB; all operate on a single positive power supply (3V to 5V) and are unconditionally stable. TriQuint innovation includes these new products:
The TQP3M9005 has a low 0.8 dB noise figure and provides 15 dB gain at 1.9 GHz; P1dB RF output is 22.3 dBm; OIP3 is 34 dBm; electrical current consumption (Idd) is 50 mA.
The TQP3M9006 on the other hand has a low 1.0 dB noise figure and delivers 13.5 dB gain at 1.9 GHz; P1dB RF output is 22.4 dBm; OIP3 is 38.5 dBm; electrical current consumption (Idd) is 90 mA.
