.
Note 2:
The lower IF frequency limit of 0MHz is limited by the external IF transformer.

BLOCKER
= 2100MHz, f
LO
= 2190MHz, using a 190MHz SAW filter on the IF port. This specification reflects the effects of
all SNR degradations in the mixer, including the LO noise as defined in Maxim Application Note 2021.
Note 4:
Maximum reliable continuous input power applied to the RF or IF port of this device is +15dBm from a 50
source.
Note 5:
