AH4
Product Description
The AH4 is a high dynamic range amplifier
packaged in a Land Grid Array (LGA) surface
mount package for applications thru 6 GHz.
The combination of low noise figure and high
output IP3 at the same bias point makes it ideal
for receiver and transmitter applications. The
AH4 achieves +41 dBm OIP3 at a mounting
temperature of 80C with an associated MTBF
of >100 years
4
. The package is a 3 X 3 Land
Grid Array. All devices are 100% RF and DC
tested. The product is targeted for applications
in the W-LAN and UNII bands where high lin-
earity is required.

Test conditions unless otherwise noted.
1. T = 22C, Vdd = 5.0 V, 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. Degradation of OIP3 occurs at low temperatures. Minimum typical OIP3 at -40C is +35 dBm.
4. MTBF calculated with channel temperature at 155C.
