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.
