Link Microtek, a manufacturer of RF and microwave components and subsystems, has launched a range of broadband microwave combiners for use in high power amplifier systems (HPAs) for applications such ...

What every RF design engineer needs these days is a good all-purpose IC RF amplifier. You don’t want to have to design basic circuits like this yourself. Yet the need is always there for a gain block ...

This article started because a good friend of mine dropped a Panasonic SA-XR50 switch-mode amplifier to me for some basic bench test. This article will NOT be a review of that unit, but an ...

The high power consumption and limited performance of traditional 802.11a orthogonal frequency division multiplexing (OFDM) systems has delayed the adoption of 802.11a and dual-band WLAN products. The ...

Mouser Electronics is stocking a 5G linear RF amplifier from Qorvo. QPA9822 is designed for 32-node mMIMO (massive multiple-input and multiple-output) antenna systems found in wideband 5G NR (new ...

Wideband power amplifiers (PAs) are notoriously inefficient, especially due to the high peak-to-average power ratio (PAPR) in wireless telecom and other base station transmitters. The PA necessitates ...
