Hi team,

Data only shows the 1db input freq bandwidth, what's the 3db input freq bandwidth?

Can we provide the input freq plot up to 2Ghz?

Thank you.

Hi Lilian,

Please see below for app note regarding TRF370417 input bandwidth

http://www.ti.com/lit/an/slwa076/slwa076.pdf

the app note is a more realistic measurement with inclusion of board (PCB) and device parasitic.

Data is taken out to 1 GHz where performance is ~ 3dB down. This is a gradual slope so it looks possible to extend with linear decrease in output power.
