Anadigics introduces small- cell wireless InGaP PAs for Band 5
The devices, manufactured using an advanced indium gallium phosphide HBT MMIC technology, offer reliability, temperature stability, and ruggedness
Anadigics, has unveiled the AWB7125 and AWB7225 small-cell power amplifiers (PAs).
enable wireless infrastructure solutions that are more thermally-efficient, consume less power, enable higher throughput, and provide greater coverage and range.
The AWB7125 wireless infrastructure PA provides +24.5 dBm linear output power, while the AWB7225 provides +27 dBm linear output power. Both power amplifiers are optimized for WCDMA, HSPA, and LTE small-cell base stations operating in the 860 MHz to 894 MHz frequency bands. Anadigics’ complete family of small-cell wireless infrastructure power amplifiers is manufactured using the Company’s exclusive InGaP-Plus technology to achieve best-in-class efficiency, linearity and thermal performance.
Pre-production samples of the AWB7125 are available now. Engineering samples of the AWB7225 are available now for qualified programs.
Sofradir boosts performance of HOT MCT infrared detector
The firm’s newest L-HOT MWIR tool, based on mercury cadmium telluride technology, offers thermal equipment makers power efficiency with no trade-off in detection range
Both devices are optimised for Band 5 WCDMA and LTE applications, including picocells, enterprise- class femtocells, and high performance customer premises equipment (CPE).
Anadigics’ complete family of small-cell power amplifiers provides a combination of high output power, efficiency, and linearity.
“The rapid growth in mobile data usage is driving carriers to seek cost effective methods to increase network capacity, especially in dense geographic locations,” says Glenn Eswein, director of product marketing for broadband RF products at Anadigics. Small-cell devices, such as picocells and femtocells, provide carriers with an economical, high performance solution that can be deployed quickly.”
Anadigics’ small-cell power amplifiers have been developed specifically for these applications, and
Sofradir, a developer and manufacturer of infrared detectors for military, space and industrial applications, is touting a prototype High Operating Temperature L-HOT MWIR integrated detector cooler assembly (IDCA) that offers a significantly improved detection range over earlier models.
Sofradir says the L-HOT MWIR demonstrator meets system integrators’ requirements to reduce SWaP (Size, Weight and Power) in military equipment.
“Producing infrared detectors that are compact, lighter and save energy is driving much of our developments at Sofradir,” says David Billon- Lanfrey, VP R&D at Sofradir. “L-HOT MWIR ensures that customers get a high operating temperature IR detector with all the gains and no trade-off in image quality and NETD in order to keep the highest detection range.”
NETD (Noise-Equivalent Temperature Difference), the signal over noise ratio of the IR detector is an
