EME228-2.5G KIT Description:

The EME228-2.5G Multiplier was designed to be used with a 564MHz or 1128MHz Local Oscillator to provide a multiplied 2256MHz output to suit the Mini-Kits EME228-13CM Transverter for the 2.4GHz band. The design uses low cost FR4 PC board material and takes around 1 hour to construct, and uses SMD components to make the design compact in size, and reproducible in performance. The maximum tuning range of the filter is from around 1.6 to 2.5GHz, but when used under 1.9GHz the filter response is not flat and requires increasing of the filter coupling capacitors. A 0dBm input drive @ 564MHz is required to produce up to +11dBm output at 2256MHz.

EME228-2.5G Performance Tests:

EME228-2.5-Plot1
EME228-2.5G frequency response when tuned to 2256MHz. The Multiplier can also be used as a 30dB high gain amplifier.
EME228-2.5-Plot2
EME228-2.5G frequency response when tuned to 2400MHz. The Multiplier can also be used as a 30dB high gain amplifier.
EME228-2.5G-Output
EME228-2.6G output when driven with a 564MHz 0dBm input. The output at 2820Mhz is the mixing of 2256 and 564MHz and could be reduced with low pass filtering if required.
