Amplifier characterisation |
|
|
The goal was to characterise the new amplifier (AP1053). For a practice, I did the characterisation of the old amplifier.This test is similar to that reported in Elog ID 13602.
- Attachment #1 shows the schematic of the setup for gain characterisation and Attachment #2 shows the results of gain characterisation.
- The gain measurement is comparable with the previous results. From the data sheet, 10 dB gain is guaranteed in the frequency range 10-450 MHz. From our observation, the gain is not flat pver this region. We have measured a maximum gain of 10.7 dB at 6 MHz and it has then decreased upto 8.5 dB at 500 MHz
- Attachement #3 shows the schematic of the setup for the noise characterisation and Attachment # 4 shows the results of noise measurment.
- The noise measurement doesn't look fine. We probably have to repeat this measurement.
