General Description
Aeroflex Laboratories Incorporated model ARX4435 ARX4435FP generation monolithic transceivers which provides compliance with Macair H009 data requirements model ARX4435 ARX4435FP perform front-end analog function inputting outputting data through transformer H-009 data bus. Design these transceivers reflects particular attention active filter performance.This results word error rate with superior waveform purity minimal zero crossover distortion. ARX4435 series active filter design additional high frequency roll-off provide required harmonic distortion waveform without increasing delay characteristics significantly. Efficient transmitter electrical thermal design results internal power dissipation temperature rise high duty cycle.
