Product Description
The AG402-86 is a general-purpose buffer amplifier that
offers high dynamic range in a low-cost surface-mount
package. At 900 MHz, the AG402-86 typically provides
15 dB of gain, +32.5 dBm Output IP3, and +17 dBm P1dB.
The device combines dependable performance with
consistent quality to maintain MTTF values exceed ing 100
years at mounti ng temperatur es of +85°C and is housed in a
SOT-86 (micro-X) industry-standard SMT package.
The AG402-86 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 AG402-86 will work for other various applications
within the DC to 6 GHz frequency range such as CATV
and fixed wireless.
