Hi All,


I'm looking for a suitable attenuator covering the following low frequency range.

- Digital step and 6 bits DSA

- Attenuate 21dBm or 12 dBm input  to 10dBm

- Input signal frequency range is from 400kHz to 100MHz

Please take a look at the attached attenuation performance of the four parts. HMC624A shows flat attenuation

until very low frequency. Does HMC624A cover my requests, or do you have better part?
