Dear Sir,
This is Gordon Liu of WNC in Taiwan.
I want to use OPA2674 be a RF PA(13MHz).
Its OP1dB is only 19dBm on the below circuit that don't meet datasheet 350mA@12V.
Could you teach me where wrong is??
| 12V DC_In (mA) | Pin (dBm) | Pout (dBm) | Gain (dB) |
| 30 | 0 | 12 | 12 |
| 32 | 1 | 13 | 12 |
| 32 | 2 | 14 | 12 |
| 34 | 3 | 15 | 12 |
| 36 | 4 | 16 | 12 |
| 40 | 5 | 17 | 12 |
| 42 | 6 | 18 | 12 |
| 44 | 7 | 18.6 | 11.6 |
| 46 | 8 | 18.9 | 10.9 |
