The AG303-86 is a general-purpose buffer amplifier that
offers high dynamic range in a low-cost surface-mount
package. At 900 MHz, the AG303-86 typically provides
20.5 dB gain, +26 dBm OIP3, and +14 dBm P1dB. The
device combines dependable performance with consistent
quality to maintain MTTF values exceeding 100 years at
mounting temperatures of +85 °C & is housed in a SOT-86
(micro-X) industry-standard SMT lead-free/green/RoHS-
compliant package.

1. Test conditions: T = 25º C, Supply Voltage = +5 V, Rbias = 22.1 Ω, 50 Ω 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. The junction temperature ensures a minimum MTTF rating of 1 million hours of usage.
