Overview


ELD-RFM2028 C-BAND UP/DOWN CONVERTER MODULE FOR TEST BENCH EQUIPMENT

RF up converters and RF down converters are integrated assemblies that convert RF and Microwave signals to another frequency range for further processing. Generally, they are designed to produce an output signal frequency for a particular frequency band. Synthesized devices use a synthesizer circuit (normally a PLL) to produce the desired LO frequency. This can be used as rack-mounted as well as designed to sit atop a table or desk

The C-Band up/down converter is a two channel RF system, one is up converter and other is down converter. The C-Band up/downconverter is designed to be used in satellite communication and aerospace application such as Tx and Rx for data transmission and reception in the C-band of frequencies .The downconverter converts 4.0 - 5.5 GHz to 70 MHz/140MHz and up converter converts from70 MHz/140MHz to 4.0 - 5.5 GHz.
