The Qorvo QPQ5601 is an high-performance, high power, Bulk Acoustic Wave (BAW) band-pass filter with extremely steep skirts, simultaneously exhibiting low loss in the Wi-Fi UNII 5-8 band and high near-in rejection in the UNII 1-3 band. The filter module is specifically designed to enable industry leading capacity performance in Wi-Fi applications that result in higher power capability in more ...

Quadsat, the Danish drone-based antenna testing company, has launched its product range with an extended breadth of frequency ranges and the addition of uplink capabilities. The Quadsat range for RF measurement comprises: QS 1-18 DL (downlink tests, covering S-KU band), QS 6-24 DL (downlink tests, X – KA low band), QS 17-31 DL (downlink, KA band), QS 6-24 DL/UL (downlink ...

East Coast Microwave is stocking cryogenic isolators from DiTom Microwave, designed to operate “at or below 77K”, according to East Coast. Taking D3I4080Y as an example, it operates from 4 to 8GHz and can handle average forward inputs up to 30W, peaking at 50W. Maximum reverse input power is 2W. “The component provides more than 16dB of isolation and has ...

For RF inductor selection, José Martos and Heinz Zenkner stress the importance of evaluating inductance, natural resonant frequency, quality, DC resistance and rated current for high-frequency applications. High frequency inductors are used in a variety of industries, from consumer products to highly specialised scientific applications. Typical functions include resonance tuning, impedance matching, filtering and attenuation of high frequency overshoots in ...

The Z-Wave Alliance has announced its ZWLR (Z-Wave Long Range) specification for the European market has been completed. It’s slated to be made available to member companies in an upcoming release. It marks the first steps towards members and manufacturers within the EU region being able to begin product development plans and certification of Z-Wave devices with ZWLR capabilities, the ...

NEC has developed a RAN autonomous optimisation technology that dynamically controls 5G Radio Access Networks (RAN) according to the status of each user terminal, thereby improving the productivity of applications such as the remote control of robots and vehicles. NEC will incorporate the technology into RAN Intelligent Controllers (RIC) and conduct demonstration tests using this technology by March 2025. There ...

Infineon has introduced a ~10 x 20mm antenna-inclusive Bluetooth 5.0 (core spec) module that consumes 1.3mA receiving (-95dBm) and 3mA transmitting (0dBm). Called CYW20822-P4TAI040, it sleeps at 2μA when retaining 32kbyte of ram, or hibernates at 800nA – the latter rising to 950nA hibernating with the wake-up receiver enabled. At maximum transmit power (+4dBm) up to 250m of range can be ...

U-blox is sampling a module that combine LTE-M cellular communication (23dBm output) and GNSS for precise location finding. SARA-R520M10 is the super-set device, combining on-board an LTE-M and NB-IoT IC (v2 of UBX-R5) with the company’s M10 GNSS receiver IC, allowing concurrent communication and location-finding in a 16 x 26 x 2.2mm package. Cellular coverage is global, and the module ...
