AP4
Product Description
The AP4 is a medium power FET packaged in
a high frequency surface mount package. The
combination of high output power and high
output IP3 at the same bias point makes it ideal
for receiver and transmitter applications. The
AP4 achieves +40 dBm OIP3 at a mounting
temperature of 80C with an associated MTBF
of >100 years
3
. The package is a 3 X 3 Land
Grid Array (LGA). All devices are 100% RF
and DC tested. The product is targeted for
fixed wireless and W-LAN applications where
high linearity, medium power and high fre-
quency are required.

Notes:
1. DC and RF parameters measured under the following conditions unless otherwise noted:
22C with Vds = 8.0 volts, Ids = 200 mA, Test frequency = 800 MHz, 50
system.
2. OIP3 measured with two tones at an output power of 5 dBm/tone separated by 10 MHz. The
suppression on the largest IM3 product is used to calculate the OIP3 using a 2:1 slope rule.
3. MTBF calculated with channel temperature at 155C.
