Recommended down convert mixer for low RF frequency input, from RF 400kHz~100MHz to IF 100kHz ?

Hi all,

Our customer will develop the low frequency down converter.

RF input : 400kHz~100MHz

IF output : 100kHz

Q1:

For example, can AD831 and AD8343 be used for applications in such a low frequency range?
The input range is from 0Hz.

Q2:

For example, can A and B be used for applications in such a low frequency range?
The input range is from 0Hz.

Best regards,

sss

If it is available, can you give me advice, materials, etc. on how to design the matching circuit of the input / output circuit, precautions, etc.?
