Guerrilla RF GRF25xx family of 5GHz low noise amplifiers

Guerrilla RF, Inc., a leading provider of high performance MMICs, is pleased to announce the introduction of our family of 5GHz low noise amplifiers. The GRF25xx family is a series of ultra-low noise amplifiers (LNAs) designed for IEEE 802.11a/n/ac applications in the 5GHz band (4.9GHz to 5.95GHz). These devices exhibit best-in-class noise figures (NFs) as low as 0.6 dB across the band, along with excellent gain and high linearity. Furthermore, they can be biased with Vdd from 2.7 to 5.0 volts with adjustable current to suit linearity requirements.

Linear introduces a current-mode synchronous step-down DC/DC controller

Linear Technology Corp. introduces the LTC3875, a dual output current-mode synchronous step-down DC/DC controller that enables the use of very low DC resistance (DCR) power inductors by using a novel DCR sensing architecture that enhances the signal-to-noise ratio of the current sense signal. Power inductor DCR, as low as 0.2 milliohms can be used without a sense resistor to maximize converter efficiency and increase power density. This new DCR sensing technique dramatically reduces the switching jitter normally associated with low DCR sensing applications.

AWT Global introduces portable PIM testers with extended Tx power range

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.
