What is the IF output range of AD 8342 ??
will it support IF o/p of 25-150 KHz ??
The IF pins on the AD8342 are DC coupled, so IF output will support 25-150 kHz. You will need to use dc block caps as shown in Fig. 56, or use very low frequency transformers at the outputs.
Dear Benjamin ,
Thanks for the reply .
My requirement was actually to convert the balanced output of AD 8342 to single output which would be fed later to a filter ,, however the transformer TC1-2T as mentioned in datasheet only supports IF in range 300MHz to 3GHz while my required range is is say around 50 to 200 KHz.
Please advice as to what can be done the company replied saying :
" transformer or balun usually don’t have good performance at such low band. You may consider using amplifier to convert between single-ended and differential signals or consult with transformer/balun vendors for part-selection."
Please advice for converting differential o/p into single o/p.
The AD8129 & AD8130 are differential to single-ended receivers suitable for your applications. Select the 8129 for high gain (Av min. =10) or 8130 for unity gain. They can accept a wide range of supply and common-mode input or output dc levels. Here's the url for the product page:
