Notes for External Elements
L1, C1: Filter for upper frequency.
C2, L2: Filter for lower frequency.
Each filter is a throughpath for the desired frequency (RF or IF) and isolates the other
frequency (IF or RF) and its harmonics.
These two filters must be connected to pin 1 and pin 6 directly.
Parasitic capacitances at the ports 1 and 6 must be as small as possible.
L4 and C4 are optimized by indicating lowest IOP at used LO-frequency; same procedure
for L3.
The ports 1, 3 and 6 must be DC open.
