InGaP HBT Gain Block

Product Information

Product Features

Applications

Product Description

The AG302-63 is a general-purpose buffer amplifier that

offers high dynamic range in a low-cost surface-mount

package. At 900 MHz, the AG302-63 typically provides

15.5 dB gain, +26.5 dBm OIP3, and +13.5 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 lead-

free/green/RoHS-compliant SOT-363 industry standard

SMT package.

The AG302-63 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, CDMA, and W-CDMA. In addition,

the AG302-63 will work for other various applications

within the DC to 4 GHz frequency range such as CATV

and fixed wireless.
