Product Description
The AH103A is a high gain, high linearity -Watt
amplifier. This device is comprised of two individual
MMIC amplifiers internally and can be used with an
external interstage match for any of the mobile
infrastructure frequency bands. The dual-stage
amplifier achieves up to +46 dBm IP3 performance
with 29 dB gain.
The device conforms to WJ Communications’ long
history of producing high reliability and quality
components. The AH103A has an associated MTTF
of a minimum of 100 years at a mounting
temperature of 85
°
C and is housed in a lead-free
/green/RoHS-compliant SOIC-8 package. All
devices are 100% RF & DC tested.
The product is targeted for use as driver amplifiers
for wireless infrastructure where high performance
and high linearity are required.

1. Test conditions unless otherwise noted: 25 oC, Vdd1 = +4.5 V, Vdd2 = +9 V, in a tuned application circuit.
2. 3OIP measured with two tones at an output power of +8 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. Amp1 and Amp2 have a typical current draw of 75 and 200 mA, respectively.
