Functional Diagram
GND
The AG203-86 is a general-purpose buffer amplifier that
offers high dynamic range in a low-cost surface-mount
package. At 900 MHz, the AG203-86 typically provides
19.5 dB gain, +21 dBm OIP3, and +8 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 (micro-X)
industry-standard SMT lead-free/green/RoHS-compliant
package.

GND
The AG203-86 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.
