The Communications Edge TM
Product Information
Product Features
50 – 1000 MHz
19 dB Gain
+22 dBm P1dB
+42 dBm OIP3
1.8 dB Noise Figure
Single Voltage Supply (+5 V)
Lead-free/Green/RoHS-

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°C and is
available in both the standard SOT-89 package and the
environmentally-friendly lead-free/green/RoHS-compliant
and green SOT-89 package. All devices are 100% RF &
DC tested.
Applications
High linearity and low-noise
amplifier following a mixer
High performance amplifier
in IF path of TX/RX systems
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 = 25ºC, Vdd = +5 V, 50 system.
2. 3OIP measured with two tones at an output power of +10 dBm/tone separated by 1 MHz. The
suppression on the largest IM3 product is used to calculate the 3OIP using a 2:1 rule.

Notes:
1. The amplifier should be connected directly to a +5 V regulator; no dropping resistor is required.
2. If no DC signal is present at the input (pin 1), C1 can be removed. The gate is internally grounded in the amplifier.
3. R2 is used as a placeholder for a different application circuit. It can be removed from the circuit.
4. C2 (from the silkscreen) is not utilized in this application circuit.
