High Dynamic Range Gain Block

Product Information

Product Features

Product Description

Functional Diagram

GND

The AH3 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 °C. The AH3 is available in the

environmentally-friendly lead-free/green/RoHS-compliant

SOT-89 package.

• 50 – 870 MHz

• +41 dBm OIP3

• 3 dB Noise Figure

• 13 dB Gain

• +20 dBm P1dB

• Single +5 V Supply

• MTTF > 100 years

The broadband amplifier uses a high reliability GaAs

MESFET technology and is targeted for applications where

high linearity is required. In addition, the AH3 is internally

matched for 50 ohms.

4. Parameters reflect performance in an AH3WB-PCB application circuit, as shown on page 3.

1. Test conditions unless otherwise noted: T = 25 ºC, 50 Ω 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.
