SOT-89 Package

Applications

Product Description

The AG102 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

qC and is

available in the environmentally-friendly lead-free/green

/RoHS-compliant SOT-89 package.

The AG102 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

AG102 will work for other applications within the 60 to

3000 MHz frequency range such as fixed wireless.

1. Test conditions unless otherwise noted: T = 25º C, 50

system.

2. 3OIP measured with two tones at an output power of +2.5 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.
