Description

AKON is a leading manufacturer of RF Microwave Millimeter Wave Components and Subsystems. AKON has developed a new series of 12 BIT Digital Frequency Discriminators (DFD) covering the frequency range of 2-6, 6-18, and 2-18 GHz. 12 BIT resolution DFD’s exhibit high accuracy of 5 MHz RMS for 2-18 GHz, 3.5 MHz RMS for 6-18 GHz and exceptional 1.5 MHz RMS for 2-6 GHz. These DFD’s have been designed with input Band Pass Filters to eliminate high level out of band signals producing false output and Limiting Amplifiers with approximate 80 dB small signal RF gain with exceptional frequency flatness of ±2.0 dB, inclusive of input Band Pass Filter. Exceptionally Low frequency flatness has a direct effect on DFD sensitivity. With 4.0 dB total Noise Figure, effective operational sensitivity for 6-18 GHz band is -60 dBm.
