Can anyone suggest mixer that suits for LO range of 2.4 - 3 GHz and IF frequency of 2 GHz ?

Hi,

I am looking for a mixer chip which should have LO range of 2 ~ 4 GHz and be able to output IF frequency of 2 GHz...

Actually, in the transmitter side, we are going to mix the LO signal (2 ~ 4 GHz) with AD9361 modulated output at IF frequency of 2 GHz. Hence, on the antenna side, we will get our desired band of transmission that is 4.4 ~ 5 GHz...

In the receiver side, we will do down tuning so that we will get IF frequency of 2 GHz...

Please suggest Mixers that suits for the above...

Thanks,

Muthu

    ADI offers a large number of mixers suited for your application. Some examples are in the table linked below:

    If you can provide some performance requirements, we can better help you in selecting the best candidate.

  • Hi Shsiao,

    Thanks...We will mix the AD9361 IF output at 2GHz with external LO ADF4351 which provides 2.4 - 3 GHz to get our desired band of transmission 4.4 - 5 GHz (RF frequency)...

    Up Conversion:

    AD9361 IF output         -    2 GHz, 6.5dBm max output power

    ADF4351 Ext LO          -    2.4~3GHz, LO drive level from ADF4351 is -4dBm to +5dBm

    We will put a power amplifier that has a gain of 26dBm to amplify the mixed signal...

    Down Conversion:

    AD9361 IF Rx input -  2 GHz, Max input signal level < +1 dBm

    RF input signal range to the mixer -  4.4 ~ 5 GHz

    Please suggest

    Thanks,
