pSemi Introduces World’s First 50 GHz Digital Step Attenuator at IMS 2018

pSemi is showcasing its range of 5G millimeter (mmWave) products, that include a 40 GHz switch, two 60 GHz switches and a 50 GHz DSA at IMS 2018. This mmWave DSA is the first single-chip digital step attenuator (DSA) to support the entire 9 kHz to 50 GHz frequency range. The pSemi mmWave products deliver excellent performance across a wide frequency range.

The PE43508 is a 6-bit, 50-ohm DSA that offers wideband support from 9 kHz to 50 GHz. The PE43508 covers a 31.5 dB attenuation range in 0.5 dB and 1 dB steps, and it is capable of maintaining 0.5 dB and 1 dB monotonicity through 50 GHz. This high-performance DSA features low insertion loss, fast switching time and low attenuation error. The PE43508 also delivers glitch-safe attenuation state transitions, which eliminates the positive glitch.

Offered as a flip-chip, monolithic die, the PE43508 is easy to use and ideal for mmWave applications including 5G test and measurement, 5G wireless infrastructure, point-to-point communication systems and very small aperture terminals (VSAT). Samples are available now. For 1K-quantity orders, each PE43508 is $50 USD.

Additional pSemi 5G mmWave Solutions

The 50 GHz DSA (PE43508) joins the UltraCMOS 40 GHz switch (PE42524) and two 60 GHz switches (PE42525, PE426525) in delivering high performance at mmWave frequencies.

  • The PE42524 was the first RF SOI switch to operate up to 40 GHz. When it was introduced in 2015, it offered design engineers their first alternative to gallium-arsenide (GaAs) switches in the K-and Ka-bands. This wideband flip-chip switch delivers high isolation performance, excellent linearity and low insertion loss.
  • Supporting a wide frequency range from 9 kHz to 60 GHz, the PE42525 and PE426525 deliver exceptional performance in all key RF parameters and have a fast switching speed of only 8 nanoseconds. The PE42525 is ideal for test-and-measurement equipment, microwave-backhaul solutions and higher frequency switching in 5G systems. The PE426525 boasts an extended temperature range that extends from -55 to +125 degrees Celsius.
