AG101
GaAs MMIC Gain Block
Product Features Product Description Functional Diagram
GND
The AG101 is a general-purpose gain block that offers
60 3000 MHz
good dynamic range and low noise figure in a low-cost 4
14 dB Gain
surface-mount package. The combination of near-constant
2.4 dB Noise Figure
OIP3 and low noise figure performance over frequency
makes it attractive for both narrowband and broadband
+32 dBm OIP3
applications. The device combines dependable performance

provides a 50 ohm input / output impedance minimizing the
number of required external components.
Mobile Infrastructure
CATV / DBS The broadband MMIC amplifier is well suited for various
current and next generation wireless technologies such as
W-LAN / ISM
GPRS, GSM, CDMA, and W-CDMA. In addition, the
RFID
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

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. A supply voltage between 3 to 4.5V can be used for the devices.
