Product Description

The AM1 is a general-purpose gain block that offers

good dynamic range and low noise figure in a low-cost

surface-mount package.

The combination of near-

constant OIP3 and low noise figure performance over

frequency makes it attractive for both narrowband and

broadband applications. The device combines dependable

performance with superb quality to maintain MTTF

values exceeding 1000 years at mounting temperatures of

+85 C and is available in the environmentally-friendly

lead-free/green/RoHS-compliant SOT-89 package.

The AM1 uses a high reliability GaAs MMIC technology

and only requires DC-blocking and bypass capacitors,

and an inductive RF choke for operation.

Internal

matching provides a 50 ohm input / output impedance

minimizing the number of required external components.

The broadband MMIC amplifier is well suited for various

current and next generation wireless technologies such as

GPRS, GSM, CDMA, and W-CDMA. In addition, the

AM1 will work for other applications within the 60 to

3000 MHz frequency range such as fixed wireless.

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

2. OIP3 measured with two tones at an output power of +2 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.

4. Parameters reflect performance in an AM1-PCB application circuit, as shown on page 4.

5. Input return loss can be dramatically improved (<-20 dB) for narrowband applications as shown on

page 5 of this datasheet.
