Product Description
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. 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.

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.
4. Parameters reflect performance in an AG101-PCB application circuit, as shown on page 4. 5. Input return loss can be dramatically improved (
