Irwell transceiver update


 

¿ªÔÆÌåÓý

Hi Andy,

Your update to the IF amp/agc looks great.

Had few questions as outlined below.

If I were to use the AD8361 outside of your agc circuit as a AM demod what is signal range in dBm that it can successfully demodulate ? E.g -40dBm to -10dBm

Can you indicate the input matching component values in your IF/agc for an IF or 9 MHz or 10.7 MHz

Also could you help with calculating the diplexer values in your mixer for an IF or 10.7 MHz and 45 MHz ?

The current values in the diplexer are for 11.059 MHz.
Can you explain your component value choices for 11.059 MHz ?

I looked at the values and somehow they didn¡¯t seem to match the expectations below.

Series LC branch XL = XC = 50 x Q factor at IF freq

Parallel LC branch XL = XC = 50/ Q factor at IF freq



Kind regards
