MGA-684P8 Typical Scattering Parameters, Vdd = 5 V
Typical Noise Parameters, Vdd=5V
Notes:
1. The Fmin values are based on noise fi gure measurements at 100 diff erent impedances using Focus source pull test system. From these
2. Scattering and noise parameters are measured on coplanar waveguide made on 0.010 inch thick ROGER 4350. The input reference plane is at the
