Device Overview
General Description
The ATN10-0050CSP1 is a surface mount GaAs MMIC 10dB attenuator in a chip scale package (CSP1). This attenuator is an ideal solution for attenuating a signal and can be used in a wide range of applications. The CSP1 allows for extreme miniaturization of SMT footprint while providing die-like performance. GaAs MMIC technology provides consistent unit-to-unit performance in a small, low-cost form factor. Compensates for high frequency board losses with a positive gain slope. A 50-ohm match is maintained over the entire operating frequency range.
Features
- Small 1.5 x 1.5 mm package size
- 10dB attenuation from DC to 50 GHz
- 24dB typical return loss over operating band
- 1W RF Power
- This product embodies Marki Microwave's U.S. Pat. 11,869,858.
Applications
- 5G
- Airborne Applications
- Test Equipment
- Amplitude Matching
- Precision Characterization
- High Channel Count Systems
