Part Number: TRF37D73 I am considering using this amplifier in one of our subsystems, but the following question arises:
When activating the PWDN state: How is the S11 and S22 of the amplifier? Are the ports matched to 50 Ohm in this state?
Hi Durga Prasad,
Looking at your requirements, you need a gain >50dB which is difficult to get in one stage. You can consider Pre driver like TRF37D73 / TRF37C75 from TI in 1st stage then a Power amplifier. Unfortunately TI does not offer last stage…
Part Number: TRF37D73 Dear TI Support Engineer

Part Number: TRF37D73 Dear colleague,
Our customer plan to use TRF37D73, but datasheet only tells the MAX input power is 10dBm.
If the input power is 0dB, the gain is 20dB, whether it could achieve 20dB output power?
Best Regards,
Rock Su

Part Number: TRF37D73 Hi team,
The customer uses TRF37D73. The input power that is PA is 13dbm for TRF37D73. This 13dbm power is
output by the 433MHZ IC device. The customer needs to know what the max power when the input power is 13dbm.
Best Wishes, Mickey…
