20-W Chip Attenuator Quells Levels To 30 dB

A 2010-chip-sized attenuator designated the VGX-2010WA features wraparound terminals for solder or epoxy attachment. These 50-Ω attenuators are constructed using thick film on aluminum nitride. Attenuation values to 30 dB are available including 0.5-dB increments. Depending on the application, the VGX-2010WA can achieve VSWR of 1.3:1 to 12 GHz. Attenuation accuracy starts at 0.2 dB. The device boasts nominal thermal resistance of ~2.5C/W. It operates from -55 to +150C. According to the manufacturer, users are guaranteed a proper balance between a well-behaved frequency response and optimal thermal performance. Thus, the device will dissipate 20 W at a 100C baseplate temperature. These devices also vow to deliver acceptable thermal and electrical performance to 10 GHz. Samples and quotes are available now.
