Product Information

Product Features

Applications

Product Description

The AG403-86 is a general-purpose buffer amplifier that

offers high dynamic range in a low-cost surface-mount

package. At 900 MHz, the AG403-86 typically provides

20.5 dB gain, +31.5 dBm OIP3, and +18 dBm P1dB. The

device combines dependable performance with consistent

quality to maintain MTTF values exceeding 100 years at

mounting temperatures of +85

qC & is housed in a SOT-86

industry-standard SMT lead-free/green/RoHS-compliant

package.

The AG403-86 consists of Darlington pair amplifiers using

the high reliability InGaP/GaAs HBT process technology

and only requires DC-blocking capacitors, a bias resistor,

and an inductive RF choke for operation.

The broadband MMIC amplifier can be directly applied to

various current and next generation wireless technologies

such as GPRS, GSM, CDMA, and W-CDMA. In addition,

the AG403-86 will work for other various applications

within the DC to 6 GHz frequency range such as CATV

and fixed wireless.

2. 3OIP measured with two tones at an output power of 0 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. The junction temperature ensures a minimum MTTF rating of 1 million hours of usage.
