Pin No. Mnemonic Description
No Connect. These pins may be connected to RF/dc ground without affecting
performance.
1 to 6, 13, 14, 17 to 22 GND Ground. These pins and package bottom must be connected to RF/dc ground.
10, 12 IF1, IF2 These pins are dc-coupled. For applications not requiring operations to dc, this port
should be dc blocked externally using a series capacitor whose value is selected to
pass the necessary IF frequency range. For operations to dc, this pin must not
source/sink more than 3 mA of current, otherwise, the device does not function and
may fail.
16 RF This pin is dc-coupled and matched to 50 Ω.
23 LO This pin is dc-coupled and matched to 50 Ω.
