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 of gain, +21 dBm Output IP3, 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 and is housed in a
SOT- 86 (m icr o- X) industr y-sta ndard SMT pack ag e .
The AG203-86 consists of Darlington pair amplifiers using
the high reliability InGaP/GaAs HBT technology 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, CDM A, 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.
