Product Description
The AH102A is a medium power gain block that offers
excellent dynamic range in a low-cost surface mount
package. The combination of a single supply voltage and
an internally matched device makes it ideal for both narrow
and broadband applications.
Superior thermal design allows the product to achieve +46
dBm IP3 performance at a mounting temperature of +85
°C
with an associated MTTF of greater than 1000 years. The
AH102A is available in the environmentally-friendly lead-
free/green/RoHS-compliant SOT-89 package.
The broadband amplifier uses a high reliability GaAs
MESFET technology and is targeted for applications where
high linearity is required.
It is well suited for various
current and next generation wireless technologies such as
GPRS, GSM, CDMA, and W-CDMA.
In addition, the
AH102A will work for other applications within the 250 to
3000 MHz frequency range such as broadband wireless.

1. Test conditions unless otherwise noted: T = 25 C, Vdd = +9 V in a 50 ohm test fixture.
2. OIP3 is measured with two tones at an output power of +8 dBm/tone separated by 10 MHz. The
suppression on the largest IM3 product is used to calculate the OIP3 using a 2:1 rule.
