Isolation test chambers for 5G, mmWave, and automotive radar development

Our new compact AC520 and AC380 anechoic chambers are specifically designed for software developers of 5G / 5G NR OTA (Over-The-Air), 77 GHz Automotive Radar, and similar mmWave and microwave applications. In a crowded office where each software developer has one or multiple transmitters turned on, they are effective, small test environments and provide effective shielding for development engineers in need of live links to be able to co-exist in the same proximity.

We listened to our customers

It’s small. With a size of 52 cm x 52 cm x 52 cm, AC520 is a compact, size-effective solution for the development and test community. The small form factor, and a stackable layout, allows you to populate a wall in the engineering departments, as well as desktop placement. Our AC380 is even more compact, with a size of just 39 cm x 39 cm x 52 cm.

It’s functional. We are using our own-designed, functional 3D-printed hinges and latches in PETG or ABS plastic. Both PETG and ABS are high-performing plastics that stands up to wear and tear, as well as being resistant to high temperatures.

Our isolation boxes have two doors opposing each other. The doors, or any of the four sides, can have a DUT holder mounted (VESA layout). We have made cutouts for 50 mm fans as well to keep the air circulating.

It’s high performing. We use 50 mm pyramidal absorbers with excellent properties in the upper microwave frequencies as well as across the mmWave bands. The full comparison is listed below.

mmWave Absorber Performance

Both 50 mm and 100 mm absorber performance will suffice for most mmWave and automotive radar development, but there will be differences as you go lower in frequency.
