RF power amplifier - ADL5604-EVALZ - query

Dear Sir,

I wish to purchase the evaluation board - ADL5604-EVALZ. Though ADL5604 is suitable for a wide range of frequencies from 700 MHz to 2700 MHz, the evaluation board is configured for a specific frequency of 2140 MHz.

Could you please let me know if I can utilize the evaluation board for 1.4 GHz?. I wish to know if the board will work at 1.4 GHz, albeit at reduced performance.

With Kind Regards,
Pradeep Kumar
