iam designing mixer in ADS tool..., mixer designing was completed and implemented in ADS....applied RF and LO signals at input side , and it is single gate FET mixer ....
problem lies is that .... i applied gate bias at gate , drain bias at drain of the FET &
RF signal at 5 GHZ is -30dBm
LO signal at 5.002 is 7dBm
the desired out out signal i.e RF-LO = 20 MHz is really very bad...iam getting output power at 20MHz which is -260dBM..
there is no conversion gain for my active mixer...which is impossible...active mixer generally produce gain ....
plzz tell me the ideas or the mistakes that i made in designing ....i really need ur help...plzz reply me as soon as possible..
