AH1

High Dynamic Range Amplifier

Product Features

Product Description

Functional Diagram

GND

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 qC. 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.

4. Parameters reflect performance in an AH1-PCB application circuit, as shown on page 3.

5. Measured with -45 dBc ACPR, IS-95 9 channels fwd.

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.
