How does the new HackRF Pro perform in practical tests? We compare it with its predecessor, the HackRF One, and analyze improvements in RF characteristics.

Harbor Freight carries a broad selection of Bauer tools. But which ones are most worth your money? We combed through the ...

Ajax is a cascade of four OPA2674 op-amps, designed to amplify the signal from a DAC by around 30 dB (between 0 and 10 dBm of power, or 1 to 10 mW). The comfort zone of this amplifier is around half a ...

In two months, the CY0S team will be arriving on Sable Island, weather permitting. The first flight, on March 18, will have three team members onboard. All DXpedition gear, except for the VHF/UHF gear ...

Arming yourself with a pair of the best budget studio monitors is one of the best ways to upgrade your mixing capabilities, and you don't have to spend loads doing it. Monitors offer an open and ...

Last year, we brought you a story about the BhangmeterV2, an internet-of-things nuclear war monitor. With a cold-war-era ...

Electronic devices are components for controlling the flow of electrical currents for the purpose of information processing and system control. Prominent examples include transistors and diodes.

Abstract: In HF communication systems, harmonic cancellation for power amplifiers (PA) is challenging due to frequent frequency switching and wide operating ranges. Existing predistortion-based ...

Abstract: This paper presents a CMOS inverter-based class-AB pseudo differential amplifier for HF applications using new simple rail-to-rail CMFB circuit. The proposed circuit employs two CMOS ...
