TYPICAL RF PERFORMANCE @ 1.85 GHZ:
OISE ARAMETERS
IDS=40mA Biased at VDS=3.3V, IDS=80mA
NOTE: Typical intermodulation performance is shown above. The data is taken with the device mounted on
NP:
evaluation board tuned at 1.85GHz for low noise and gain as shown in the reference design given on page 6.
The FPD750SOT343 has enhanced Intermodulation performance with an OIP3 value of up to P1dB+16dBm.
This effect can be seen when the device is biased at ID=80mA by the bough in the 3rd order product plot line .
Biased at VDS=3.3V,
Typical Intermodulation Performance
VDS = 3.3V IDS = 40mA at f = 1.85GHz
