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 conditions unless 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 output power of +10 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. 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 given ground tab temperature can be calculated by

multiplying the thermal resistance with the total package power dissipation and adding it to the tab

temperature. ie. At 85

°C case temperature for a typical 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.
