RF Driver Amplifier (ADL5320) will it operate below 400MHz?


Just wondering if the ADL5320or similar SOT-89 packaged part might work down to 145Mhz?

I need the following specs for an amplifier:

Fout = 145MHz

P1dB ~ 20dBm

Gain ~ 12dB

    Hi Rev.,

                  Internal circuitry prevents the ADL5320 from operating below 400 MHz.

      I suggest looking at the ADL5601, ADL5602, ADL5535 and ADL5536. the ADL5601 and ADL5535 are 15 dB gain blocks and will operate at 145 MHz. THe ADL5602 and ADL5536 are similar devices and have 20 dB of gain.

    The operating frequency range for the ADL5601/02 is: 50 MHz to 4 Ghz. For the ADL5535 and ADL5536 the frequency range is: 20 MHz to 1 GHz.

    Hi Jim,

    Thanks for getting back,  Just checked those chips, they all fall a little short on the P1dB i'm afraid.

    I know I said ~19dBm, but I was hoping that your reply would be closer to ~25dBm.

    Sorry about that, I should have specified it correctly the first time round.

    Thanks all the same.
