I need to find the difference of two frequencies, so I am trying to use SBL1 double balanced mixer...

I was giving 5Vpp,1MHz on LO & 3Vpp,1.1MHz signal on RF frequency from function generator....so I should get 2.1MHz and 100KHz....but the signal i am getting is having 2.1MHz as the lowest frequency signal and another high frequency components but 100KHz was totally missing !!!


Circuit I have Build :

Please help....
 

If your SA cannot see down to 100kHz, place at the output of the mixer a simple LPF to let only 100kHz to pass. Terminate the LPF in concordance, and measure the voltage over the load to find the equivalent power level
