Product Description
The AH1 is a high dynamic range amplifier in a low-cost
surface-mount package. The combination of low noise
figure and high output IP3 at the same bias point makes it
ideal for receiver and transmitter applications. The device
combines dependable performance with superb quality to
maintain MTTF values exceeding 100 years at mounting
temperatures of +85
q
C. The AH1 is available in the
environmentally-friendly lead-free/green/RoHS-compliant
SOT-89 package.
The broadband amplifier uses a high reliability GaAs
MMIC 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
AH1 will work for other applications within the 250 to
4000 MHz frequency range such as fixed wireless, W-
LAN, and WiBro.

1. Test conditions unless otherwise noted: T = 25 oC, 50
system.
2. 3OIP 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 3OIP using a 2:1 rule.
3. Noise figure can be optimized by matching the input for optimal return loss.
