Product Description
Functional Diagram
GND
The AG101 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
10,000 years at mounting temperatures of +85 qC and is
available in the environmentally-friendly lead-free/green
/RoHS-compliant SOT-89 package.

Function
Input
Pin No.
The AG101 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
AG101 will work for other applications within the 60 to
3000 MHz frequency range such as fixed wireless.

4. Parameters reflect performance in an AG101-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.
1. Test conditions unless otherwise noted: T = 25 ºC, 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.
