Product Information
High Dynamic Range IF Amplifier
Product Description
The AH31 is a high dynamic range amplifier in a low-cost
surface-mount package. The combination of low noise
figure, high gain, and high output IP3 is ideal as an IF
amplifier for receiver and transmitter applications.
The device combines dependable performance with
consistent quality to maintain MTTF values exceeding
1000 years at mounting temperatures of +85
qC
and is
available in the environmentally-friendly lead-free/green
/RoHS-compliant SOT-89 package. All devices are 100%
RF & DC tested.
The MMIC amplifier based on GaAs MESFET technology
can be configured for IF and RF applications with various
current and next generation wireless technologies.

1. Test conditions : T = 25 ºC, Vdd = +5 V, 50 system.
2. 3OIP measured with two tones at an output power of +5 dBm/tone separated by 1 MHz. The
suppression on the largest IM3 product is used to calculate the 3OIP using a 2:1 rule.
3. Typical parameters reflect performance in an application circuit.
