Specifications
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
performance with superb quality to maintain MTTF values
exceeding 100 years at mounting temperatures of +85
°
C
and is housed in a SOT-89 industry-standard SMT 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 AG102 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.

Test conditions unless otherwise noted.
1. T = 25o C, Supply Voltage = +4.5 V, Frequency = 900 MHz, 50 ohm system.
2. 3OIP 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.

4. Typical parameters reflect performance in a 50 ohm system.
5. Input return loss can be dramatically improved (<-20 dB) with an input series inductance of 6.8 nH
for 900 MHz applications or with an input shunt inductance of 5.6 nH for 1.9 GHz applications.
