Product Description
The AM1 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
°C
and is available in the
environmentally-friendly lead-free/green/RoHS-compliant
SOT-89 package.
The AM1 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
AM1 will work for other applications within the 60 to 3000
MHz frequency range such as fixed wireless.

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.
3. Noise figure can be optimized by matching the input for optimal return loss.
4. Parameters reflect performance in an AM1-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.
