Replacement for X14 Multiplier

The National Oceanic and Atmospheric Administration (NOAA) is seeking information from industry regarding a replacement for the X14 Frequency Multiplier utilized within the WSR-88D NEXRAD Radar receiver. The current A2A1 unit has reached end-of-life and is no longer able to be repaired. NOAA is looking for ideas, recommendations, technical approaches, and best practices from industry on how to advance, redesign, replace, or provide a compatible A2A1 unit. The replacement unit must meet specific electrical, mechanical, and environmental requirements. • The replacement unit must accept a +10 dBm 57.5491 MHz CW signal and output two phase-coherent 805.6874 MHz CW signals. • The unit must have an input VSWR no greater than 1.5:1 and a characteristic RF impedance of 50 ohms. • The unit must ensure phase noise gain from the frequency multiplication process does not exceed +30 dB at any point from 10 Hz to 1 MHz offset of output frequency. • The unit must be powered by +15 VDC and draw a maximum of 300 mA. • The unit must have an enclosure that is form and fit identical to the current A2A1 unit. • The unit must meet specific environmental requirements, including operating temperature range, non-operating temperature range, operating humidity range, and non-operating humidity range.
