Device Overview
General Description
The ATN20-0040PSM is a surface mount GaAs MMIC 20dB attenuator in a DFN package. This attenuator is an ideal solution for attenuating a signal and can be used in a wide range of applications. The compact DFN package allows for extreme miniaturization of SMT footprint making this attenuator suitable for low SWaP applications. GaAs MMIC technology provides consistent unit-to-unit performance in a small, low-cost form factor. A 50-ohm match is maintained over the entire operating frequency range.
Features
- Small 1.3 x 2.0 mm package size
- 20dB attenuation from DC to 40 GHz
- 22dB typical return loss over operating band
- Low SWaP
Applications
- 5G
- Test Equipment
- Precision Characterization
- Airborne Applications
- Amplitude Matching
- High Channel Count Systems
