Product Description
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 °C & is housed in a SOT-86 (micro-X)
industry-standard SMT lead-free/green/RoHS-compliant
package.
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.
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 AG203-86 will work for other various applications
within the DC to 6 GHz frequency range such as CATV
and fixed wireless.
