AP3
Product Description
The AP3 is a high dynamic range FET pack-
aged in a high frequency surface mount pack-
age. The combination of low noise figure and
high output IP3 at the same bias point makes it
ideal for receiver and transmitter applications.
The AP3 achieves +39 dBm OIP3 at a mount-
ing temperature of 80C with an associated
MTBF of >100 years4. The package is a 3 X 3
Land Grid Array (LGA). All devices are 100%
RF and DC tested. The product is targeted for
applications where high linearity is required.
