Product Description
The AH1-1 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 AH1-1
is a specially screened version of the AH1 offering a very
narrow gain spread from device to device.
The device combines dependable performance with superb
quality to maintain MTTF values exceeding 100 years at
mounting temperatures of +85
qC. The AH1-1 is available
in
both
the
standard
SOT-89
package
and
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
AH1-1 will work for other applications within the 250 to 3
4000 MHz frequency range such as fixed wireless.

1. Test conditions unless otherwise noted: T = 25 C, 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.
