Functional Diagram
GND
The AG503-86 is a general-purpose buffer amplifier that
offers high dynamic range in a low-cost surface-mount
package. At 900 MHz, the AG503-86 typically provides
20 dB gain, +29 dBm OIP3, and +16 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.

GND
The AG503-86 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.

1. Test conditions: T = 25º C, Supply Voltage = +6 V, Rbias = 22.1 Ω, 50 Ω System.
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.
