Some measurement results for the 27dBm RF amplifier that was descripted in an earlier post. Results are shown for two builds, without and with additional SAW filter.
27dBm RF Amplifier builds
Frequency range 300MHz – 3GHz. Input -20dBm, normalized to 0dBm, hence coax cables and output attenuator are calibrated out of the measurment loop.
Gain over frequency range 300MHz – 3GHz.
Second RF amplifier build with 1575MHz SAW filter installed.
Gain and 3dB bandwidth @ 1575MHz
