Anritsu has created a 9kHz to 54GHz spectrum analyser module that can be added to other test set-ups. MS27200A-0754, as it will be known, has 110MHz real-time analysis bandwidth, where it can can stream and capture IQ in 32bits, and -164 dBm DANL. That said, much of this performance requires options to be purchased and added. “The module is self-contained, ...

Component distributor Richardson RFPD is stocking a 5 to 8GHz GaAs pHEMT low noise linear amplifier from Guerrilla RF, and has added it to its design support service. Measuring 1.5 x 1.5mm (DFN-6), GRF2110 is aimed at WiFi 6/6E, small cell and wireless infrastructure. It operates from 2.7 to 6V, drawing 70mA at 5V. Power is applied to the output ...

A mixer-first sliding-IF architecture has been chosen by a PhD student to create a 300GHz radio receiver front-end using 300GHz Ft (450GHz Fmax) transistors from a 130nm SiGe BiCMOS process. According to the thesis of Sumit Singh, studying at University of Oulu in Finland, down-conversion of the 300GHz carrier is initially by a local oscillator at two-thirds of the carrier, ...

Adding a third terminal to an LED can make it 50% faster, according to researchers at the iGaN Lab, led by Professor Haiding Sun at the University of Science and Technology of China (USTC). They took the idea of driving an LED via a hybrid-T network, which combine ac and dc drive signals, one stage further, building a capacitively-coupled ac ...

Samtec has created a line of RF connectors that mount to the edge of PCB by bolting rather than soldering. They measure only 9.5mm from side-to-side where they sit on the PCB and are under 8mm from top to bottom (see photo) “These connectors are commonly used in a lab setting for high-frequency test and measurement and evaluation boards,” according ...

Harwin has launched a range of multi-GHz multi-pin board-to-board connectors that tolerate slight misalignment, shock and vibration. Branded Flecto, they are double-row, with up to 160 contacts, and come in three pitches: 0.5, 0.635 (.025in) or 0.8mm, for mated board-to-board spacings between 7.2mm and 29.9mm. The connectors are two-part – one for each board. Controlled flexibility comes from making one ...

Pico Technology has introduced a 3GHz bandwidth display-less oscilloscope with 10Gsample/s maximum performance. Called PicoScope 6428E-D, it has four 50Ω input channels and four input ranges per channel (±50, ±100, ±200 and ±500mV). Maximum vertical resolution is 12bits. “The new oscilloscope extends the capabilities of the existing PicoScope 6000E Series, making it an ideal tool for scientists and researchers working ...

United Monolithic Semiconductors has introduced a 24.25 – 30.5GHz combined output power amplifier, input low-noise amplifier and transit-receive switch. Called CHC6054-QQA, it is manufactured from AlGaN/GaN-on-SiC (gallium nitride on silicon carbide) and gallium arsenide die, both from 150mm wafers. Packaging is 4 x 5mm QFN. It “typically exhibits an Rx gain of 18dB with a noise figure of 3.2dB, and ...

Spectrum Instrumentation has introduced a way to parallel its 12bit 10Gsample/s data acquisition cards up to eight channels, that can also produce 16 12bit channels at 5Gsample/s. Called Star-Hub, it works with the company’s recently introduced M5i.33xx series of PCIe digitisers. “The Star-Hub option is installed by mounting a single piggyback module onto any of the M5i series cards in ...

Teledyne LeCroy has announced a 65GHz 12bit oscilloscope. Called 8650HD, two 65GHz channels can be operated though 1.85mm 50Ω connectors, or it can be switched to four 33GHz channels. It is part of the 8000HD family of scopes, with six models from 20 to 65GHz, up to 320Gsample/s (two channels) and up to 8Gpoint of acquisition memory (200Mpint/s/ch is standard) ...
