• PGA-103 Low Noise Amp 0.05-3GHz

The PGA-103 amplifier is ideal as a Very Low Noise high dynamic range amplifier for use between 50MHz and 1.3GHz.  The amplifier is also suitable as a driver amplifier for complex RF waveforms, and produces up to +21dBm output on 400MHz.   The PGA-103 is specified to 4GHz, but the gain is very non linear and is 10dB lower at 1.3GHz compared to 100MHz.  Please refer to the PGA-103+ Data Sheet for further information.  A 78M05 regulator is mounted under the board for +7 to 15vdc operation.
