EMWIN 1690 MHz to 137 MHz Down Converter Now Available
(Rev: 01/01/2020)
High Performance Converters with 10 MHz external reference.
The Model 5923 series converters are available for 50, 70, 144, 432, 1296, 2304 and 2400 MHz. They are designed using a one or two stage pHEMT MMIC LNA, with each stage followed by a filter, which provides excellent image rejection. It has a PLL local oscillator which is locked to an external 10 MHz reference. The external 10 MHz reference is filtered internally by a 10 MHz crystal filter which helps to improve phase noise and rejection of spurious signal which might be on the reference.
Also employed is a high dynamic range double balanced mixer followed by an IF filter. Some models offer a choice of IF frequencies.
