High Linearity Amplifier

www.DataSheet4U.com AH102A Medium Power, High Linearity Amplifier Product Features 350 – 3000 MHz +46 dBm Output IP3 14.5 dB Gain +27 dBm P1dB MTTF > 1000 Years Internally Matched • Single +9 V Supply • Lead-free/Green/RoHS-compliant SOT-89 Package • • • • • • Product Description The AH102A is a medium power gain block that offers excellent dynamic range in a low-cost surface mount package. The combination of a single supply voltage and an internally matched device makes it ideal for both narrow and broadband applications. Superior thermal design allows the product to achieve +46 dBm IP3 performance at a mounting temperature of +85 °C with an associated MTTF of greater than 1000 years. The AH102A is available in the environmentally-friendly leadfree/green/RoHS-compliant SOT-89 package. The broadband amplifier uses a high reliability GaAs MESFET technology and is targeted for applications where high linearity is required. It is well suited for various current and next generation wireless technologies such as GPRS, GSM, CDMA, and W-CDMA. In addition, the AH102A will work for other applications within the 250 to 3000 MHz frequency range such as broadband wireless.
