BELOW SHOWS THE TESTED RESULTS OF THE PROTOTYPE KITS
|
The Above Chart 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 3256MHz ( 3400-144MHz ) 2M IF Filter respose was down by only 13dB which is poor & is way off the -16dB for acceptable image rejection. 2970MHz ( 3400-432MHz ) 70cm IF Filter response was down by 50dB which is very good. 2104MHz ( 3400-1296MHz ) 23cm IF Filter response was down by 59.5dB which is very good.
The Above Chart shows the response of the EME101 Multiplier Kit 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. Compared to the other chart above the Multiplier efficiency drops off below 3.370GHz, but still has usable output to around 3.325GHz
The Above Chart shows the Spurious output levels with a 1.15GHz +3dBm Input.
