Specifications

Product Description

The AH103 is a high gain, high linearity ½-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 28.5 dB gain.

The device conforms to WJ Communications’ long
history of producing high reliability and quality
components. The AH103 has an associated MTTF of
a minimum of 100 years at a mounting temperature
of 85°C. 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.

Test conditio ns unles s otherwise noted.

1. T = 25ºC, Vdd1 = +4.5 V, Vdd2 = +9 V, Frequency = 800 MHz in a tuned application circuit.

2. The frequency of operation & bandwidth is determined by the external interstage match.

3. 3OIP measured with two tones at an out put power of +10 dBm/tone separated by 10 MHz. T he
suppression on the largest IM3 product is used to calculate the 3OIP using a 2:1 rule.

4. IS-95, 9 Channels Forward, Pk/Avg Ratio = 11.5 dB at a .001% probability

±750 kHz offset, 30 kHz BW, Channel BW = 1.23 MHz, frequency = 880 MHz.

5. The worst-case junction temperature for a g iven ground tab temperature can be calculated by
multiplying the thermal resistance with the tot al package power d issipation and adding it to the t ab
temperature. ie. At 85°C case temperature for a typ ical device, the worst-case junction temperature
would be = 85°C + (9 V * 0.2 A + 4.5 V * 0.075 A) = 129°C.

6. The junction temperature ensures a minimum MTTF rating of 1 million hours of usage.
