To set up the RF, use the following settings and measure the
output at the EVAL-ADMV4630Z RFOUT port:
►
REF_IN port: reference frequency = 25 MHz, 4 dBm, and dc
block is needed.
►
IF input: IF frequency = 4.1 GHz, −30 dBm.
►
The gain is at minimum attenuation. Note that the chip tem-
perature is higher than 25°C for the reference frequency and
IF frequency conditions and there is part to part variation.
The gain may be lower than the typical specifications in the
data sheet.
