PCB mat'l: FR-4;
Two Layer: (31 mils; w/plating)
Off of Pin 2: 60 mil microstrip line for 902
MHZ to 928 MHz and 75 mil microstrip line
for 890 MHZ to 915 MHz and 120 mil for 824
MHz to 849 MHz. Lumped element off of Pin
2 would be 1.2 nH to 2.0 nH to ground
depending on frequency band of interest.
