Linear Technology announces the LTC3639, a 150V input-capable synchronous buck converter that delivers up to 100mA of continuous output current. It operates from an input voltage range of 4.5V to 150V, eliminating the need for an external transient suspension device. The LTC3639 utilizes internal synchronous rectification and a programmable peak current-mode design to optimize efficiency over a broad range of output currents.
TriQuint Semiconductor Inc., a leading RF solutions supplier and technology innovator, has released two new dual matched low noise amplifiers that are ideally suited for balanced high performance RF design configurations. These integrated LNAs are highly linear and offer very low noise figures, high output and include automatic shut-down capability for use in Time Division Duplex (TDD) and Frequency-Domain Duplex (FDD) applications.
AWT Global has launched a new line of portable passive intermodulation (PIM) testers with an extended carrier power range: the PIM+ series. These systems are equally suited for testing macro cells as well as outdoor and in-building DAS installations. While 2 x 20 W (2 x 43 dBm) carrier power is the reference for standard for PIM test systems, the new PIM+ offers an extended adjustable power range of +15 dBm to +44 dBm for each carrier.
