EME101 Kit Description:

The 3.4GHz Multiplier is suitable for use with the EME79 / 154 Transmitter Kits for constructing an ATV transmitter for 3300MHz. The frequency range of the stripline filter is from 3310 - 3620MHz @ 3dB. The board could also be used as an amplifier, or filter for construction of 3400MHz equipment. The Multiplier is designed for a +3dBm 2mW input @ 1100MHz for a >10dBm 10mW output @ 3400MHz.

EME101 Kit Tests:

EME101-GAIN

The plot above shows mainly the filter response of the EME101 Multiplier Kit using a 3.275 to 3.65GHz -5dBm input signal. The -3dB points were measured at 3.310 to 3.620GHz ( 310MHz Bandwidth ). Maximum output 3450MHz was measured at +16dBm saturated with a -4dBm input signal ( 20dB Gain ). For use as a Filter for a SSB Transverter the following measurements were made on the above for various Frequencies that would be Image frequencies. A I/F frequency at 144MHz and below would not be acceptable if the board was to be used to construct a Transverter, or receive converter.

At 3256MHz ( 3400-144MHz ), the 2M I/F Filter respose was down by only 13dB which is poor and is way off the -16dB for acceptable image rejection. The 2970MHz ( 3400-432MHz ) 70cm I/F Filter response was down by 50dB which is very good, and the 2104MHz ( 3400-1296MHz ) 23cm I/F Filter response was down by 59.5dB which is excellent.

EME101-MULT

The plot above shows the response of the EME101 Multiplier using a 1.1 to 1.2GHz +3dBm input signal. The -3dB points were measured at 3.3426 and 3.6039GHz. The ripple is due to the ERA3 Multiplier efficiency with different input frequencies, not the filter. Compared to the other plot above the Multiplier efficiency drops off below 3.370GHz, but still has usable output to around 3.325GHz

EME101-SPURS

The plot above shows the output spectrum using a 1.15GHz +3dBm input signal.
