Product Description
The AH11 is a high linearity amplifier for use in digital communication systems. It combines low noise figure and high intercept point into a low-cost SMT solution. This device extends the linear efficiency advantages of WJ’s AH1 to higher power levels by combining two internally matched die. This dual-amplifier configuration allows for the optimal design of balanced or push-pull operation. The amplifier can also be used for single-ended operation in each branch of a diversity receive system.
A mature and reliable GaAs MESFET technology is employed to maximize linearity while achieving low noise figure. The package is a thermally enhanced lead-free/green/RoHS-compliant SOIC-8 package thus allowing the device to achieve an MTTF greater than 100 years at a case temperature of 85 °C. All devices are 100% RF and DC tested.
