NOTE:
1. R1, R2 and R8 are optional.
2. R4, R5 and R6 form T-attenuator with a loss of 1 dB.
For 0 dB loss, R4 and R6 are removed, and R5 is a 0
short.
3. R3 and R7 are normally open.
4. FLT BP recommended is a Murata filter: SAFC836.5MC90T-TC12.
5. The microstrip on pin 4 is bridged to ground via 0
0402 size resistor.
The recommended setting is at maximum of PCB.
6. The microstrip on pin 3 is bridged to ground via 0
resistor. The
recommended setting is at a distance of 35 mils from edge of device.
