The combination of low noise figure and high output IP3 at the same bias point makes it ideal for receiver and transmitter applications. The device combines dependable performance with superb quality to maintain MTTF values exceeding 100 years at mounting temperatures of +85 °C. The AH3 is available in the environmentally-friendly lead-free/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. In addition, the AH3 is internally matched for 50 ohms.

Test conditions unless otherwise noted: T = 25 ºC, 50 Ω system. 2. 3OIP measured with two tones at an output power of +5 dBm/tone separated by 10 MHz. The suppression on the largest IM3 product is used to calculate the 3OIP using a 2:1 rule. 3. Noise figure can be optimized by matching the input for optimal return loss. Absolute Maximum Rating Parameter Rating Operating Case Temperature -40 to +85 °C Storage Temperature -55 to +125 °C Supply Voltage +6 V RF Input Power (continuous) +10 dBm Junction Temperature +220 °C Operation of this device above any of these parameters may cause permanent damage.
