CBG9326

PRELIMINARY CBG9326 GaAs HBT MMIC DRIVER AMPLIFIER, 3.0 - 4.5 GHz DESCRIPTION The device is provided in an EMSOP8 package. BLOCK DIAGRAM VPD 1 GND 2 RFIN 3 GND 4 NF ID EN TI AL The CBG9326 is high efficiency GaAs HBT MMIC driver amplifier which operates between 3.0 and 4.5 GHz. The amplifier is packaged in a low cost, surface mount 8 leaded package with an exposed base for improved RF and thermal performance. The amplifier provides 19 dB of gain and +25 dBm of saturated power from a +3.3V supply voltage，and 23dB of gain and +26dBm of saturated power from a +5V supply voltage. Power down capability is available to conserve current consumption when the amplifier is not in use. Internal circuit matching was optimized to provide greater than 40% PAE.

There is no damage to device with only one parameter set at the limit and all other parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device. ESD HANDLING: Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device. This device must be protected at all times from ESD when handling or transporting. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD handling precautions should be used at all times.
